i always wanted a MM or MMX game like this, but more of a 3rd person perspective a la Transformers: WfC or FoC (i thought a wii-mote would be great for this or a mouse). and i have no problem with X being a little gritty, but the X series was always a little surreal, with bright colors through a robotic landscape, not some drab grey corridors.
also, X has a human face, even if he's a robot, not some weird white and red sensor array or a big red X across his face. that x across his face mask (which i totally get needed a face mask when in battle) is total shit.
the design itself otherwiese isn't that bad, but it would be better if it was in-between what they designed and the cartoon versions of X. i like the idea of X being able to temporarily grab enemy weapons and having his blaster arm morph to match, but i really hate X losing his plasma cannon for a machine gun. really? i'd rather have the graphics resources making his weapons look insane and variable weapon damage and death animations for enemies than having a overly-articulated X that looks too much like Michael Bay's transformers.
