The more I think about this, the more ideas I come up with. Unfortunately, most of them are incompatible with each other. 
What I'd really look for in a mech game is something that plays in under 2 hours (or under 1 hour), something where the typical game involves 4 to 8 mechs per side, something where a single mech's rules can fit on a single playing card (or half sheet of paper), and something that can encompass mechs from different genres so that I can have the western military styled mechs and the eastern anime styled mechs under the same roof.
I want to use a heat system, to retain the idea that specific weapons or components can be shot off of your mech, and to retain the idea that maneuvering for the right angle is an important part of playing the game.
But of course these are all concepts, not specifics, and I want to reinvent the wheel a bit rather than just copy battletech. In particular I want to skip the simulationist "every mech is a composite of standardized parts" idea from battletech, and make each mech a custom design. I think that will be better for the game in the long term.
I have a good heat system written. What sorts of things do you guys look for in a mech game?
