In my estimation, Metroid Prime (one) is the second best overall game GC game out there. Given that you can get it for around 15 beans, you should definitely pick it up. As far as the gameplay goes, it's pretty solid (esp the jumping) but it doesn't necessarily follow your classic FPS conrol scheme, so it may take some getting used to. The icing on the cake for me was the presentation. The graphics, story, music, level design, ect all gave me that old Metroid vibe.
