I've played little bits of Super Metroid, Metroid 1, and Metroid Prime. I've finished Metroid 2. (I got it way back when it came out. Bought it with my Kool-Aid points. :P) None of them have really been able to hold my interest. I kind of had to force myself to finish Metroid 2. Actually, I quit playing soon after I got it. It wasn't until years later when Smash Bros. came out that I started playing it again. I was like "Oh, hey, Samus. She's cool. I should play Metroid 2..."
