I personally like the Metroid Prime series a lot. Funny thing is that most Nintendo fans claim that it isn't a FPS.

For the sake of all that doesn't suck though, don't ever try Metroid: Other M. I love Mr Khan, but his opinions on the game are warped.

Too late, I already bought, played, finished and been disappointed by Metroid: Other M.

What a lousy game, huh?

I get angry when Nintendo fans defend it.  It makes us, as a group, look stupid.
