Recently, I've picked up Kirby Air Ride and Wario Ware: Mega Party Games for GC. Those games RULE!

Wario Ware is the kind of game where you need at least 3 people playing to really appreciate it. You can be Disco dancing, fighting robots, ninja training, racing paper airplanes (Which sound like cars...

), and *gasp* WORKING TOGETHER, all in 15 minutes.

And then there's Kirby Air Ride...talk about an awesome game.

There's a mode where you just explore this HUGE city and the area around it, looking for power-ups and new stars\bikes to ride, so you'll be prepared for the competetion ahead. And while you're exploring, crazy things happen like a meteor shower, thieves running off with rare items, or everyone's vehicle goes crazy and starts going crazy fast. Plus, you can find pieces of special stars...
I don't see why those games get lousy reviews. Maybe I'm just a LITTLE biased, but they really are awesome.
