Latest game such as Pokemon Omega Ruby & Alpha Sapphire,Super Smash Bros 3DS, Shovel Knight, & Persona Q: Shadow of the Labyrinth. Which are the latest great games released so far. In the future, monster hunter 4 ultimate would be a very high anticipated game for the 3ds in 2015. Also there's going to be a Legend of Zelda Majora Mask 3DS a game that many LOZ Fans are dying to wait for. If you are a big fan of Bravely Default then Bravely Second will be announced probably around next year.
I feel like 2015 would be a great year for Nintendo.
