I was going to write up F-Zero and Mario Cart first, as they are the first games I fired up, and it makes for a good compare and contrast. However, I never went back to them after my inital looksie because OH MY GOD WARIOWARE, INC. Genius game of the (previous) decade. Seriously whoever came up with the idea of 3 second microgames should have secured himself a place in video game design history.

Perfect mobile game. Perfect have on hand at all times downloadable game.

Also it has a perfectly playable Dr. Mario clone embedded in it. Who knows what other wonders it has hidden inside. (Yes the internet, but I prefer to be surprised.

This game is everything good about Japanese game design. Perfect design, incomprehensibly delightful 'story'. I could write more, but then I wouldn't be playing more WarioWare.
