I know that they're making an MMPORG, but what about just plain old conventional pencil and paper with dice game like AD&D, Shadowrun, Rifts and so on? Sure Rifts is indeed apocalyptic, but let's pull back a bit to the Fallout Universe, ne?
Who'd be interested in a game series like this? And what game system would you like it based upon? GURPS? Shadowrun (extremely ballanced game)? AD&D? D20 system (may it rot in hell) or something original?
