I'm buying one today for two games: Luigi's mansion dark moon (huge fan) and Splinter cell 3DS (another one I'm a huge fan of). --- Steam: http://steamcommunity.com/id/IJustWantMyFriendBack Gamefaqs is like Walmart. Both have similarities when it comes to censorship. Quite annoying.
To be honest, I didn't seriously consider getting a 3DS until they brought the Zelda bundle out, so you could say I got it for OoT 3D (because I never really got into the original and I've always been better with handheld games). I usually get consoles because of upcoming games, though - like if I know there's going to be a sequel to a series I like, I buy the console and see what else is worth picking up. I'm glad I got a 3DS relatively early so I didn't have to buy one for ACNL or Pokémon XY.
Animal Crossing & Rune Factory 4. I wasn't that excited for Pokemon around the time I got mine though, which was this summer. It was all the Animal Crossing buzz that actually got me to take the plunge (I got the pink XL). Also, I knew Rune Factory was coming out soon and I loved 3 so I knew I was going to get that too. --- ~*~*im a princess*~*~
