The Good: Tons of neat, exciting, and wacky mini-games, good sense of humor
The Bad: Not enough of them, uninteresting stories and characters
WarioWare is a game that set a standard for mini-games. While it's simple at heart the game is fast paced and very exciting. With 5 second mini-games and only one word clues to figure out what to do it makes your heart race and keeps you hooked. The game has over 100 mini-games and they are so simple they just need a few button pushes and you're done. You go through sets of mini-games and a "bass game" at the end of the set.
The mini-games are wacky, neat, and just plain fun. While it's not the longest game in the world you will come back and play the mini-games a few more times just for the hell of it. Each set has a mini story and character attached to it but it's nothing interesting or anything to remember. What makes WarioWare fun is the speed and timing in everything. I actually prefer this over Flash Focus (DS) since it sharpens your "eye skills" better than any game you could ever play. Pick up WarioWare in your bargain and you'll get hooked!
