It doesnt have to be rated "M" for me to like it. I just want a decent game that doesnt have mario characters in it. Every popular game has them. Strikers, paper mario, that Brawl game, mario party. Its just getting old.
And as for Metroid, it will be a great game but not halo. Main reason- No online play. THats a bust. I will not buy a shooter without online. Just gets boring.
