So I picked up MegaMan Battle Network 5: Double Team DS about a week ago and it's incredibly addicting. It's not exactly a new game, but it's a lot of fun and I'd recommend it to anyone who likes MegaMan games and RPG's. It's a cool game because it sucessfully mixes RPG elements, Collectable Card Game elements (only they're battle chips), board game elements, and real time fighting together really well. I've probably played it for 7 hours so far and I'm not even 1/4 of the way through.

So yeah, good game. Plus it's two for the price of one since there are two teams you can join.
