Great to know you're enjoying it! I loved mine when I got it as well...

Some games to put on your radar:

1 - Tearaway - as you're a Nintendo supporter you probably enjoy platformers and this is the best 3D platformer on the Vita! it's very creative and innovative

2 - Gravity Rush - my favorite game on PS Vita and my first platinum, I've loved this game, every moment of it! The gravity mechanics might feel a little hard to control at first but keep on trying you'll just do it fine! Mainly the Gravity Slide, once you get used to it, you'll be the faster Gravity Shifter out there!

3 - LittleBigPlanet Vita - This is simply the greatest LBP game out in the wild, it makes great use of the Vita functionalities, making each level more fun then the last one! Had a blast on this 2D Platform + Minigame collection

4 - Killzone Mercenary - If a FPS is what you seek, you came to the right place! With the hability to play anywhere, an addictive multiplayer, amazing special weapons (the MANTIS ENGINE is so effing cool!) it has graphics as amazing as a PS4, it's a PS Vita mustbuy!

5 - Uncharted: Golden Abyss - Another game with just as amazing graphics as the PS3, it has amazing uses of Vita's functionalities with an amazing adventure with a lot of treasures to collect!

6 - Sly Cooper Thieves In Time - one of the best platformers on PS2 is back and better then ever keeping it's Stealth Platformer mechanics, with a lot of collectibles and special costumes that give Sly new skills!

7 - Persona 4 Golden - Want some JRPG? P4G is the perfection on what it does!

8 - Soul Sacrifice - An action RPG game with Monster Hunter mechanics, deep story where you need to choose sacrifice, for ultimate power, or have compation and save the beasts! Probably one of Vita's best games, Muliplayer is great!

9 - Muramasa Rebirth - Remaking one of Wii's most stylish game, it brings amazing graphics on Vita's screen, the best localization it could have (dialogues on the Wii are pretty much rushed and empty) with 4 new DLCs telling stories of new characters

10 - Final Fantasy X | X-2 HD - The latest mustbuy Vita game on the west! It brings back one of the most amazing JRPGs on PS2, with HD graphics and the Final Mix version of the game that was never released on west
