Not sure to be honest. I know that Pokemon X & Y will release shortly after I get it, not to mention all the classics already on the system reinvented for the handheld... My Girlfriend is buying it for me so... Hopefully something good!

Smash Bros will also be great on the go! Do you have one?

you could save your money and invest it.

Invest into some Paintball equipment, then have fun with friends.

Buy something fun and dangerous, like and air rifle or a cheap dirt bike.

Or a Vita, if you want something gaming related.

A pocket pussy and a copy of the witcher 2 to use it. 

Monster Hunter

Get an Ouya =)
