I play Metroid games all the time. I beat 1, 2, super, and fusion. I plan to get a gamecube just for prime and when that new metroid game comes out. Mission zero, I think. I plan to get that, and all hail metroid prime II. Thats being made =)
I also had a site dedicated to metroid games, althoguh it was breif and never got off the ground, but meh.
Magus, Majin, me, and Ryoko are Teh Metroid addicts
