Metroid Prime + any FPS, especially Halo, in a topic is instant fodder for one of the most massive flamewars possible on the net.
While this isn’t a bad topic in concept, I really don’t think it’s going to result in anything but OMG HALO VS METROID PRIME all over again, so I think this needs to be locked… PM me if you really think it should stay open though, I seem to be locking a lot of topics lately so maybe I’m just being overzealous…
