My 3DS says 46 minutes... I definitely played a ton of this. I'm not sure that I made much progress, but it was awesome to just roam around and play the minigames on road trips. I don't think there's ever been a better minigame collection.

If it wasn't for it's horrible controls, this would be my favorite 3D Mario game.
And where is Waluigi?! Come on, Nintendo. Give our purple plumber boy a chance.

This is an excellent remake of the original. I love the concept of taking old classics and adding new content to them. This adds 30 new stars, a handful of new levels, four new playable characters, and fun minigames. This is mandatory playing for all owners of the Nintendo DS.
