Why not do both? Have a character selection screen at the beginning of the campaign mode? There's bugger all story to these games so I imagine it'd take the studio about 30 minutes to produce the alternate audio and storyline to suit the additional character.

I'm still surprised GS didn't mention the awful sound quality in this game.

This is the kind of score RE4 and 5 should have received as well. Generic action games.

Hawken is just a generic FPS with a mech theme, riding the coattails of the Mechwarrior franchise.

Mech Warrior Online is actually a mech game.
