There are a lot of good platformers here such as Rogue Legacy and Giana Sisters, so it would be nice if they had official controller support (especially with rumble). Or do all games that support controllers here already have rumble?

If a game supports Xinput, it should have rumble support regardless of which distributor it comes from. A Big Picture mode would be nice, though, for people playing on HTPC's.

I hook my PC up to the TV frequently, so a Big Picture Mode alternative would be very useful for me.
