Help with Deciding

Hey Guys me and my brother haven't been using our 3DS so we decided to buy a game but we dont know which one we should
so far we only have Devil Survivor<--which was not that worth it, Street Fighter IVWhat do you guys think we should get first?
-Zelda OoT
-Mario Kart
-Super Mario 3Dor whichever can you guys help us decide what to buy that would be great

Star Fox 64 3D

Zelda in my opinion

Mario 3D made me think that my 3DS was worth the purchase.

Mario 3DS would be the only reason I'd purchase a 3DS.

Kart or Land?

Replying to #6

Land

Hmmm can't decided.. but i think i'll just get Mario Land 3D so my sister can play it as well
