I don't think we do hate hard on FPS.
We hate hard on the same generic WWII with big teeth enemy alien footsoldier and bald space marine muscle pumped protagonist that's been played a million times before.
We hate on FPS devs who consistently ignore Nintendo in all its forms.
We hate on FPS games whos' sole contribution to developent is a new shader for shrapnel and skin, requiring purchase of Windows Vista and a DX10 card.
We hate on FPS games that declare single player dead.
We hate on devs who insinuate that FP is the only real way to play a game.
Generally this is what everyone here should be hating, or at least getting tired of.
Oh, and Metroid doesn't fall into any of those. Sure there's more exposition, and I think the Metroid purists are a bit miffed at that. But I hear towards the middle of the game there's more of the loneliness we've all come to expect and love in Metroid.
I actually think Nintendo fans are looking forward to FPS games, and no one's going to deny how exciting Half Life 2 and Bioshock are. In fact, I think many of us are dying for a Wii port of HL2 or Portal or Mirror's Edge.
We'll never get one though. Because the Devs are bastards, blind to the majority. Metroid could outsell Halo 3 and it still wouldn't persuade those asses they should stop ignoring us.
