3DS Game Recommendation!

Besides Mario Kart 7, there are only a few 3DS games that I can think of that have most of those features.

Dead or Alive: Demensions has:

Wi-Fi
Streetpass & Spotpass
Multiplayer
Good Gameplay (IMO)

Tetris Axis has:

Wi-Fi
Spotpass
Multiplayer
Good Gameplay (IMO)

Including the games that others have alrady postded, those are the only ones that come to my mind at the moment.

Here are some games you should watch out for that are coming out next year:

Kid Icarus: Uprising
Resident Evil: Revelations
Animal Crossing
Heroes of Ruin
Tekken 3D: Prime Edition

^ They all have some type of multiplayer ^

If you'd like to know more about any of those games, take a look inside the 3DS Info Thread.

You said January, but if you can wait until Febuary then get Resident Evil. If you can wait until March get Heros of Ruin. Looks to have amazing multiplayer.
