I dunno if I'd call Metroid Prime "shit". I only played the original. I couldn't really get into it, being 12 and bad at FPSes when I last picked it up, but it's really unique and I don't think there's been a better attempt at making a free, open world in an FPS. It retains that whole Metroid sense of discovery and exploration and FEELS like a Metroid game while being in 3D and even though I couldn't get into it, it was by far the best 2D to 3D conversion for any sidescrolling shooters from the SNES days.
I should really try it again. I really always loved the whole world of Metroid but I could never really just get into any of the games. I ended up picking up Fusion last summer after not touching it for four or five years and plowing through it and I enjoyed it a lot, though. Maybe this summer after I get through my backlog of Christmas games I'll get to Prime. I need to at least finish MGS3 already though.
