Has there been any word on when the rules of the game will be released? I know FFG tends to put out rule books online before the game actually becomes available for purchase. I don't particularly remember playing the original game (although I know I owned some cards) and would like to familiarize myself with the system before buying it. OK who are we kidding I'm gonna buy it any way but I'd love to know how the game works!

The rules haven't been released yet, but expect them to be posted on the game's support page before August 16th (its release at Gencon).

Till then, you can brush up on the original Netrunner's rules through several online portals.

An HTML version is available here: http://www.incabrain.com/netrunner/rules.htm

Downloadable versions are available here: http://www.netrunneronline.com/rules/

The minutia might change, but the big picture will probably translate relatively intact.

*edit: Additionally, if you have a buddy willing to test the waters with you, you can play the original for free (all cards) through the Netrunner VASSAL application available here:
