Some of the things I've been playing lately:
* Games with Loads of Content
- Pokemon X/Y
- Monster Hunter 3U (huge fanbase, but pretty fun...bad learning curve for beginners, although)
* Puzzle-Based Games
- Luigi's Mansion: Dark Moon (it's fun, although the boss fights and extra secrets are frustrating
- Spirit Camera: The Cursed Memoir (good, but it's short, and you need the booklet that comes with the game with play, and technically pretty bad - the camera needs bright light to register your moves)
* Buy if You Didn't Play the Original:
- Tetris Axis
- Zelda Ocarina of Time (remastered version looks flipping amazing, but there are still some flaws with it)
