My wife loves Fire Emblem, and there were a few other games that sounded good, so FE was the deciding factor. The first game we actually bought was KH:Dream Drop Distance, and it almost made me regret buying the 3DS for a while.
I don't buy consoles for games, I bought it cause I needed an upgrade (still had an original DS) and I liked it. I mean c'mon, it plays games in 3D with no glasses, you really needed a better reason than that? --- MapleHoodOG
