If we go on with what others have said and also what was in Miskatonic Horror then likely what would be included would be:

• Extra cards for every deck type in the game (These would not interact with other expansions)
• Extra cards for every deck type in the game that integrate expansions together (For example, in Miskatonic Horror it adds cards for the expansion boards to interact with other expansion boards as well as mechanics included in the small box expansions.)
• An extra mechanic (In Miskatonic Horror it was Organisations that were added (University, FBI and Mafia). I'm not sure what it would be in Talisman. I guess maybe different guilds or societies might be cool? Could add Churches and Cults for the various characters who are part of those. It could be fun.

I really don't see them introducing new boards, though. They could introduce variants for individual squares (or for the Inner Region), though…

Could you elaborate on the sections below?

   An example of how Miskatonic added cards that allow boards to interact with boards

  in the last point, not so much about the types of mechanics, but 'how'.  For example I've mentioned Academies or Monasteries where either skill can be learned or craft/strength enhanced.

   Since there are so many cultists (mostly Dragon oriented), I rather think this a cool idea.  Of course we like our cultist 'enemies', so maybe if they are defeated there is a roll, if they win, they are moved to their Temple for healing - and live to fight another day (in which case you don't get them as a trophy, but maybe get to rob them of some 'cult' weapon they have (Cultist Tool deck?)

 To sum up my day/night integration theory,

   As we had new event cards, "Lunar Event" that must change the day to night and vice a versa, perhaps new events (like I'm posting on some other threads) that imply without specifying, could  have "Day/Night Optional event" (where 'event' or 'lunar event' verbiage is place.

I had to take a quick look through my box set to remind myself of some specific examples but here you go:

• You're asked to deliver a letter from a location in one board to another. (If you do it then you immediately get transported to the other board and receive an award.)
• Another example is giving areas in the expansion board the ability to use mechanics from small box expansions (For example in Miskatonic Corruption was introduced in 'The Black Goat in the Woods' but in Miskatonic it added cards so Corruption could be used in the extra boards (Dunwich, Innsmouth and Kingsport).
• Innsmouth Horror introduces the 'Innsmouth Look' mechanic. Miskatonic adds that Kingsport can also use this mechanic.

For Talisman you could maybe have things like:

• Your sewer in the City leading to the Dungeon idea.
• A modified version of the magic portal at the end of the Dungeon that can teleport you to the other expansion boards.
• Adding Day/Night interaction for expansion boards (Part of me thinks that the Dungeon would ignore Day/Night being underground. For the Forest I would check out the Hollow/Unhollow home brew so a cool idea of Day/Night there.)
• Additional Alternate endings involving visiting the other areas. (Maybe the Lord of Darkness gets the Crown of Command?)

In Miskatonic the organisations did different things:

• For the FBI, you could feed it Clue Tokens to place FBI agents on the location you're standing in. If you had enough agents to overcome a Monster then it was killed and you lost on Agent. In effect, if you had enough agents they could clear an area out without you having to lift a finger. Also, they can protect allies from being killed by putting them into 'protective custody' which involved hiding them in an expansion board and allowing you to come find them if you were willing to spend the time and resources to get them back.
• The University allowed you to gain degrees as well as ask them to fund 'research' for you.
• The Mafia could help you out by giving you money (If you joined them), helping you out if you get arrested or hurt. Also they would sell you items if you could afford the premium (The advantage was you could buy anywhere and not just by visiting a store).

For Talisman it could maybe be something like:

• An 'Adventurers Guild' that could let you place adventurers on squares who you could spend to help defeat monsters who appear there. The guild could perhaps also sell you things if you were in the city.
• There's already Academy adventure cards so not sure if there would be a University equivalent.
• Mafia could be a thieves guild. You could perhaps hire thieves to steal from other players or they could sell you things from the Oasis?

That's just a few ideas of the top of my head. Perhaps it might get the ball rolling.

* Quest cards in each corner expansion that makes it rewarding for the player to visit a place that they normally wouldn't in a playthrough, especially reasons to go to the inner region. This may also reward the player to visit another corner region. If the Forest expansion is wisdom-focused then it might make sense that the Dungeon gets a card that asks the player to go to the forest, while they have the quest they have +2 wisdom in the forest, the Forest gets a card that asks the player to go to the dungeon and while they have the quest they have +2 strength*
 

Inner Region Quests:  Place (new?) objects cards on various spaces, a certain gem that must be retrieved from the mines, a magic object the Vampire has in the Tower, so on.

Cross-corner quests: Rendition a dangerous Dark Elf from the Forest to the Dungeon Cell. A special flower or herb in the Highlands is requested by the Doctor in the City.  The Frost Queen takes the Prince/ess from the character who finds them and forces you to trade her back for an object from each corner; trinkets or similar. 

 Without creating extra/complementary boards, you could also expand play on spaces like the Castle, Lost City, etc by having a alt.ending sized card with options, in stead of the space's instructions:

   Castle: If you return the Prince/ess , the King will double the gold if you additionally accompany him/her to City to see the doctor (or a City-Royal Compound). This could be interesting, because maybe *any* character can receive the reward if they deliver, so Characters may challenge the character with the Prince/ess and take them if they win.   Additional play options, if you don't have the Prince/ess : Find a secret passage to (roll) 1) Dungeon Library 2) Lost City 3) King's square 4) the Chapel 5) Cave behind the Waterfall in the Forest {I'm making this up!} 6) The Crypt in the Inner region

 Thanks for taking the time to research and post this.  These sound very interesting, I like!  I like the idea of other end bosses competing for or obtaining the Crown.  I suppose ultimately an alt.ending that works with all expansions would be something like, Eagle King, Frost Queen, Lord/Darkness combine to fight all 3 Lords. The Reaper is the referee. Characters try to gum up the works, or choose allies themselves (kinda like the Blood Moon alt.ending?, or a reverse to the Light Bearers one?)

Actually this sounds impossibly bizarre and hard to figure any reason or advantage to characters, any thoughts?

Draii said:

Would you see this as a hard or soft cover book that would be in some expansion?

For this type of rulebook to work it would have to be released near the end or as the last expansion to minimize errata.

DLC rulebook would do the trick of answering fans faster, is easier to update, make correction and add-on to existing text as expansion and new mechanics are released.

Draii said:

Yes I like this idea, and since it would be only one miniature we might have a better chance of getting it prepainted.

 Draii said:

FFG might do a limited-partnership with a company who specialized on poker table and card shuffler (but honestly I don't see FFG manufacturing card shuffler or big carrying case but I might be wrong

Draii said:

And then we could shuffle all those corners to select which one is gonna be used for a specific game.

This is also interesting as it will add so much replayability, no two game will be even close to be the same.

Jimmythecritic said:

So would it be like a bigger game box with storage inside or something more casino style like a carrying case and card shuffler?

Tavicz said:

Do you mean something like an "updated wizard" released 1.1 with new ability and more balance with the new character, yes I agree with the fans saying that character from the last couple of expansion are much stronger than those from the base game.

Tavicz said:

Do you just want more of them or do you want stronger enemy?

Tavicz said:

Yes this would be great

0beron said:

Yeah, I wasn't notice too way back when it became clear that each expansion would be on it's own, the idea is that a customer who own 1 expansion might not have the previous 2 and would be reluctant to buy an expansion who might have 4 or 5 adventure cards out of maybe 60 that you would have to throw away if you don't own said expansions,

Personally, I don't think that people who buy Talisman will also buy the corner big box expansion and the dragon, the board with 1 or 2 corner look so incomplete.

Also, I don't think that 4 or 5 trap door or other mean to be sent to other regions will stop a potential buyer from purchasing an expansion if said expansion as an appealing story or flavor to add to the game. Hey, it might even give the extra push needed buy a big box expansion and improve sales. 

Velhart said:

Agreed, but do you think they should keen on adding extra mechanic to the game or only new character, adventure and spell cards

Velhart said:

Strange, I've see lots of tread from other poeples asking for more monster and enemies!!!

Velhart said:

Seem to me you want all cards from 2nd edition to make it to 4.5, does that include Timescape?

Velhart said:

Yeah well it would be nice if Talisman would get the same treatment that "City of Thieves" and "Arkam Horror" did for their Miniatures which is to release them in box as a prepaint set.

0beron said:

Let's hope this one will manage to survive

0beron said:

Heh, I wouldn't worry too much about ideas being "ignored". I suspect it is just because only FFG truly know what is in store and whatever we might like, it is all in their hands.

Though Miskatonic Horror is a BIG box expansion (bigger than normal really), I think it would suit Talisman to have this type of thing as a SMALL expansion. Not sure whether they would go with it, but adding around 30 cards per corner deck, and another 10/12 for each Dragon deck might be a nice number along with a few characters and endings. It keeps the cost down to a more manageable level too and would be more of an impulse buy for those worried about the true value of the box.

It would probably make for a good addition after the 4th corner is released and people are more concerned about expanding what they have, rather than introducing yet more boards. It could also be another exercise in cost-effectiveness by recycling a bit of artwork around all of the large expansion boards… Goblins in the Highlands, Constructs in the City, that type of thing.

We seem to follow the same line of reasoning about putting more interaction between corners.

0beron said:

Most business model seem to disagree with this kind of statement, let me state the example of comic book, crossover, team-up, guest appearance have been used since the 60's to increase interest and sale on lesser know series or characters, and it worked because they keep on using it today.

Agreed not everybody will buy all the set, I can see poeple buying only small expansion or the dragon as a big box, but not when it comes to corner boxes, it would look odd to have only one or 2 corners, so my guess is that fan who invest in one corner will eventually complete all four  and the relevance to have a small expansion that help the interaction between all four is a more than natural way to make the large Talisman landscape seem whole.

Your idea about a scenario, a mystery or quest small expansion is a good one, I like it, many possibilities there.

Hi, it seem to me that small expansion are more into a theme and adding new mechanics to the game and BIG corner box deal more with increasing the land.

So if you suspect a SMALL expansion to tie-in all region, do you expect also new mechanic to make region more interactive between themself and the main board?

You mention 30 cards for each regions 10/12 dragon deck card but what about spell cards? Spell card could be useful for travelling from one region to another

(can I say "Magical Trap Door", "Vortex", "Walk Through Ethereal Plane" and such.).

The "cost-effectiveness by recycling a bit of artwork around" thing will positively be a helping factor in a yeah or neah decision.
