I like the art style for Gravity Rush. I was hoping Gravity Rush 2 would come out for PS4 because I think an open world game like that would have a lot more potential, but it looks like its only for vita again.
Persona 4 golden - JRPG perfection... I hope persona 5 this year will reach the same heights.
Hotline Miami - seriously this game is so much better on vita, the visuals look so much sharper than the other platforms you can play it on and it controls real nice too with the dual analogue ...make sure you wear headphones to fully appreciate how insane the soundtrack is too.
Spelunky - I just wish it controlled a little better, the dpad i find isnt great for some of the harder platforming sections....the analogue stick works slightly better but still not precise enough in my experience.... i got it cross buy and whenever i play it on ps3 i tend to die a lot less.
