I’ve ranted about this before but so far, I’ve seen nothing to fill my criteria. Maybe I should send some mail to SJG, Hero, Chaosium or even–SHUDDER—Hasbro to get them cracking on this.
I’d prefer the flexibility and realism of GURPS or Hero since the physics engine software would hide most of that complexity from players and gamemasters that don’t have the patience for such things. Table-top, paper based games need something like this!
