For some reason I skipped over BW/BW2 when they came out so I grabbed a copy of White 2 a couple weeks ago, and holy moly what a great game. I love that there is no tedious tutorial in the starting town, you are given your starter mon, running shoes, town map and set free. Lots of great Pokemon in this gen as well. I thought gen 4 was the goat but gen 5 has really impressed me. my goal is to beat it before USUM comes out so I can get all the pokemon I've caught in Platinum and White 2 transferred to the 3DS games and have a solid low-level team ready straight out the gates.
Speaking of USUM, the games apparently leaked late last night/early this morning. I'm waiting til my copy arrives to play but they are looking pretty fun!
