My oldest son is 6. He has been playing his old Nintendo DS [and by old I mean OLD. Original blue DS. It's a tank.]. I've let him play my 3DS XL a few times, and he LOVES it. So for Christmas we decided to get him a 2DS with Mario and Pokemon X. We didn't want him to mess up his eyes with the 3D, but the 2DS is perfect and it's cheaper! What are you getting your kids for Christmas?
