This is what the devs over at http://www.hawkengame.com/blog/ are working on.
This game emulates reality so well, I almost got motion sickness from watching the video. It makes me tear up seeing how far graphics have advanced. I MEAN COME ON, DYNAMIC SHADING ON THE HUD WHICH BY THE WAY IS EMBEDDED INTO THE MECH, A++ GAME ALREADY.
The only thing that could make this game better would be destructible environment; other than that, this game is insane! I would give everything to work at their studio to work on Hawken.
