Welcome aboard! Your project sounds like a tough challenge, but that what makes them all the more satisfying, right? As for realistic role-playing games, you might check out YAGS, which is geared for low-fantasy. It's designed and maintained by Samuel Penn, one of the regulars on this list. The link is on the FRPGC's website, under the Games section, or you can just go to: http://www.bifrost.demon.co.uk/games/yags/ There was a gratis game called DragonSpawn that was meant to be very realistic, and it looked promising, but now the site has no links to download it... maybe I should e-mail the guy. -- J.
