I HATE Metroid Prime Hunters. The control completely sucks IMO (on top of not being a real Metroid game). The PSP is *WAY* better for shooters, both because of the hardware and controls. And yes, I actually know this because I've *PLAYED* multiple shooters on both systems.
I'd hate the lousy control this game would have to have, but it would be kind of nifty to see it otherwise.
I have to agree...why not just release it with a slight makeover? It's no like Halo is that distinctive anyway. Just give the person a different generic power suit, change the graphics a bit, and ship it.
