WarioWare + Wiimote= Good times. WarioWare + Wiimote + friends= Classic.
The graphics in WarioWare could be given a 10 or a 0 depending on when you walk into the room. Some of the games or sections look like they could be drawn by a 7 year old using his off hand in about 5 minutes. Meanwhile, some of the games look very sharp, and the story sequences look vibrant and lively. The sound is superb... especially the gentleman who reads the descriptions of every new "form" (a.k.a how you hold the Wiimote to play a given microgame). The gameplay is excellent as well. This game lacks value, clocking in at just over 4 hours to completely beat the single player game.
For anyone looking for something way, way out there and a game that you can play with a whole bunch of buddies, look no further. If you don't like WarioWare, you don't like fun.
