Why wouldn't it support roleplaying? Sure, the tabletop game is all about the battles, but books have plenty of material about the life of people in the Imperium.madbird-valiant said:I would have said Mass Effect usually, but a universe like 40k doesn't really support roleplaying. Unless you follow the life of a soldier who does absolutely nothing but go to different planets to kill stuff, it's not really gonna happen.
Homeworld got my vote. I always loved hte idea of the Battlefleet Gothic stuff, but they were too small and too expensive for me to bother with. A Homeworld-esque type RTS would be perfect.
