Project X zone next week. I played the demo, and have been playing JRPGs all my life, and it didn't make any fucking sense to me at all, at least the combat...HOWEVER, it does look and sound pretty fucking awesome, so maybe its just slightly odder learning curve.
Super Mario 3d land is great and much better at the end of the normal game.
Animal Crossing is fucking amazing, it is just a hard game to play for hours and hours on end, which can be hard when you REALLY just want to keep playing. The real world clock and how everything is at such a long pace (it is always TOMORROW WE WILL HAVE IT DONE FOR YOU) can drag some sessions down, but it is prefect for quick 10-20 minute chunks.
Honestly, I got bored with Fire Emblem pretty quick. I found it got very easy once you start getting people grouped up and leveled.
If you like adventure games and don't mind a DS game, Hotel Dusk is fantastic. Its a bit low key at first, but there is something about that hotel that just stays in my head. Every few days I keep wanting to go back and play that.
