Buying games for young teenagers

[nallkun]

My niece has become quite the gamer and is obsessed with Legend of Zelda. I'm looking to get her into different types of games. She owns a PS3, Gamecube, Xbox 360, DSI and 3DS. She plays the hell out of Ratchet and Clank and Guitar Hero. Any help would be appreciated especially since I am buying her some games for Christmas.

Thanks!

Hope this is allowed. If not, I'll delete.
