Congrats on the purchase!
A lot of people here have given some very good suggestions, but you NEED to get these 3 games in particular:
- Demon's Souls
- 3D Dot Game Heroes
- Valkyria Chronicles
I'm fairly positive you'll enjoy those games.
Rockstar: Announce Bully 2 already and make gamers proud!
Kojima: Come out with Project S already!
