Vanquish, GOD HAND, Wonderful 101.
Yes! Even though those games (with the exception of Vanquish's troll ending) felt pretty self containted there's so many ways they could be expanded on gameplay wise that i'm surprised nobody has attempted to emulate what those games did.
I'd like a new Onimusha similiar to the first two. Jean Reno is a cool dude but keep him out of my video games.
