What 3DS Launch Title is Your 'Must-Buy'?

[Ninpanda]

Resident Evil: Revelations, if it's a launch title.

If Revelations isn't a launch title, Paper Mario.

If Paper Mario isn't a launch title, Mario Kart.

If Mario Kart isn't a launch title, RE: Mercenaries.

And if Mercenaries isn't a launch title, none.
