I was hoping this would be about how stupid andrex has been recently.
On topic, a 3DS is basically a must have (or will be.) It's got some quality games, although not much recently. M3DL is a solid game, but I don't think it's as challenging as the ex and himu have been talking about, even in the post game worlds. Mario Kart 7 is a great MK. Kid Icarus is garbage, but you should probably play it. Some peeps love it. Haven't player RE, but I don't ever play those games. KH3D is the next game I'll get, I hear it's pretty sweet.
