I've recently had a chance to play a little bit of Metroid Prime 2: Echoes. I remember renting a Nintendo Gamecube back in Dec. 2002 for a weekend to play Metroid Prime non-stop for a holiday weekend. This sequel came out two years later, and I have a chance to play it now (having a Wii, which is backward compatible with the Gamecube). It's been as much fun as the original, and shows the thought and depth that go into some of Nintendo's games. Plus, it's a fun refresher as Metroid Prime 3 for the Wii is coming out soon.
