Pleeeeeeeeease don't go with 'mecha.' My interest in this will completely die if someone uses a 'mecha' with a crapton of stuff that don't even sound realistic.

The difference between 'mech' and 'mecha' in my opinion is that 'mecha' with the 'a' means anime mech. And no. Mecha do giant sword fights with oddly advanced weapons with oddly outdated war. Mechs are walking tanks where a mech half the size of a mecha could smash a hole in it from sixteen miles away before the mecha even saw it. 

There is reason we have Marines rather than carbon-fiber armored knights.

[i]not for me[/i], my interest will be lost so quickly that it'd be more akin to the movement of particles in a particle accelerator than anything.

But other than that, looks uber cool.
