I believe if you have a gameboy player though and hook it up with Metroid Prime, you unlock the original metroid on your Metroid Prime game... that also happens when you beat Metroid Prime too, i think.
Either game is really good though. if you've never played the original metroid, I'd go with zero mission, it's fun. Fusion is good too, but stick with the original...
