Already have one, I'd appreciate another or two:
https://www.playhawken.com/?ref=dug4tlfpScotty is just a negative nancy.
It could be, say, like Armored Core with Gundammy robots flying everywhere pew pew pew shhh boom Itano Circus/Macross Missile Massacre with tons of Roboteching and middle fingers to physics and common sense abound.
Actually Armored Core isn't that bad about it, and I like Armored Core.
So instead I'll just go with what I think's best: play MWO and Hawken and Netmech and Armored Core.
I'm still holding out for a CryTek space sim. I'm pretty sure the engine is flexible enough.
CryEngine 3 should be able to do it.
I'd rather have a Descent-like game from one of the versions of CryEngine though, and it'd probably be easier to make.
