There was a game that came out a few years ago. I don't remember much, but here's what I do:

The game came with a 3 page long shortcut keys list

You could pilot spaceships, and even eject yourself out of it and float around the area, all in First person

You could pilot ships, airplanes, tanks, ATV's, etc. as well as walk/run around with your weapons

I think it was released as a budget game, and I know it made it to stores, that's where I bought it.

I know it's not much, but if anyone can find it or something similar, please let me know.
