I just picked up Nintendo's latest for the GBA: WarioWare, Inc. Mega Microgame$ and they aren't kidding! This little gem is chock full of mini games taken from classic NES games such as DuckHunt, ExciteBike, BalloonFight, DonkeyKong, even Dr.Mario makes an appearance, as well as others from all types of inspiration. They say there are over 200 games in all, but the best part of it is not even the selection, it's the rate at which they are thrown at you randomly and for only seconds a stage... you either do it or you don't. If you miss too many, you have to start from the beginning again. There are even several two player games that get unlocked by progressing through the game, and are played simulataneously on the same GBA! One player takes the right shoulder button, the other the left. Madness!
This is a great little game to take with you when you want to play a quick game of something, as it is unlikely you will ever be bored with the variety it offers.
Highly recommended... A+
