Helldivers - I originally passed on this game because of the developer, but trying it now it's actually pretty cool. I wish they were a little less survival-stingy with resources as ammo management takes a lot more attention than I'd like. Crushing people under air drops is a pretty consistently great time.
Marvel Heroes - They just released a big patch that added controller support, and while the game is still super basic with horrible art/animation (I think literally every other Marvel game that has been released in the last five years - including cell phone games - looks better) it's now a lot more fun to play with direct control. They did a really good job there, although inventory management still uses a cursor instead of item selection.
Gran Turismo 5 - It's good but I mostly went back to this because of Steam Link incompatibility with racing wheels. Feels like feature overload at times, as though they were trying to cram in everything they could think of just for the heck of it. I'll probably skip 6 and wait for the PS4 entry.
But now that there's a pseudo-official workaround for the Steam Link to support racing wheels, PS4 controllers, etc. I'll probably be going back to Assetto Corsa and Project Cars soon.
