I know this won't exactly answer your question, but rather than look for that game that accomodates that setting. You might want to see which system you can teach your players that will go ok with the game and setting and they won't spend hours debating how does it work, why it is bothering, why the hell can't I hit anything, HP, etc etc.
Alternatively, do a small run of the system you want to use before shoving them straight into the real game.
