Don't play the FPS Metroid games then, aka the Prime games. I've always found the sidescroller ones superior either way, and if you ever feel like giving it a shot, then Super Metroid is a good start, or as Diddy Kong suggests Zero Mission.To be honest, I never really got into Metroid myself. I watched a play through of the Other M. I played Metroid Prime 3 in my entirety. I didn't really give the game a fair shake, but it just felt like a Halo knock-off to me. I am sure there are better Metroid games out there. They just aren't for me. If I am going to play a shooter, I would rather play Call of Duty or Battlefield.
Its huge lack of direction and non-linearity leads me to warn people that they should play this as the last sidescroller, it's a good game, but only once you've come to love Metroid already.Make sure you don't forget about Metroid II.
