you shouldn't make a game like that, but you could make it a little humorous. you know, like in hogan's heroes for example And change the name!
you could make tons of wacky missions, like "steal the commandants armyboots",
"paint his dog purple", that's all i could pull outa my butt.
and it could end with the commandant release them, because he's so sick and fed up with their pranks.
I'd sure play that
