Are you a PS+ subscriber, Del? If so, you can grab Hotline Miami and Gravity Rush for free, which I can't recommend strongly enough. It kinda sucks the memory cards are still so expensive, because between PS+ and the bundle I got, I can't fit all my free games on a 16GB card

Sonic All-Stars Racing Transformed is a well-polished, stupid fun kart racer that I have been having a blast with. It might not be free anymore but it is cross-buy, meaning you get both the PS3 and Vita versions if you buy one. The free copy of Hotline Miami works the same way.

I've also been playing a lot of Little Big Planet Vita, which is of the same quality of the console versions, and any DLC costumes you've purchased can be carried over as soon as you boot up.
