Recently took the plunge and picked up a 3DS XL, and found myself walking out with a copy of New Super Mario Bros 2. I justified the purchase of the game as "well, my wife will want this game eventually, anyway", but I've really enjoyed it so far. I didn't particularly enjoy the original on the DS, but Mario seems to move much more smooth and fluid on this game. That and the inclusion of the Racoon tail make all the difference in this game being fun, because while the coin count is an interesting addition, it hasn't been the reason why i've been exploring the nooks and crannies of the levels.
I also went ahead and got the Kirby collection. I didn't realize it was selling for $40, which was a bit disappointing, but I still feel it's worth it. Just wish more Kirby's Epic Yarn music was on the soundtrack.
