Disgaea

WHY

It's a fun game and the stories are funny X3

Uncharted is a huge reason. It has phenomenal voice acting and story.

Yeah get them all ^.=.^ They are awesome!

Infamous 1 and 2. Both of which have a fantastic story and voice acting. it's one of my favorite games to date. If you liked sly cooper you will absolutely love Infamous.
Another good one is Kingdoms of Amalur. Although I'm sure you could get it for the xbox 360, its still worth buying. >.> the only way I can think of describing it is it kinda like Skyrim in the sense that there is a hell of a alot of side missions so be done as well as your character is very customizable. Which I enjoyed very much.
I also recommend the Rachet and Clank future series if you enjoyed the previous PS2 games in that series. The story is more complex than those of its past and the graphic are like phenomenal its almost like you're watching a pixar movie.
I think that about does it for my recommendations, hope that helps. :)

Disagea 4, Infamous, Valkyra Chronicles,anything from the Atelier sereis, Arcana heart 3, Hyper dimensional Neptuina mk2.

..that's all I can think of right now..

You should get Motorstorm Apocalypse because it has the best car customization (and maybe someone else like me has it for playing online).
