Welcome to the forums man! (:
& I somewhat agree with your comment about there not being enough games on it yet, but in my eyes it's the type of games that are on the market right now for the 3DS (which are mainly not my cup of tea).
There's a huge FC thread somewhere on these fourms, but you can also post your FC in your user information.
