Okay, been doing some Deep Thinking here, and have come up with several ideas for games that I really would love to find a way to get pitched, or make myself (assuming I ever get around to learning advanced programming and animation skills needed)

1) A mech based game, similar in function to Mechwarrior, possibly even a MW5. Barring that, 40k universe playing as a Titan Legion Princeps.

2) A squad-based FPS styled in the manner of the Battlefield series, with each player in command of their own squad of bots. There would be no aircraft allowed for use by players because they tend to skew the battle, and no one seems to know how to use the damned things.

3) A space combat sim; preferably placing the player in command of a large scale warship, rather than the small fighter craft they usually do. In multiplayer, this could be improved upon by allowing several players per ship, handling things such as various gun batteries, whether main armaments or point defense, as well as letting other players play as fighter pilots.

Thats all I can think of off the top of my head, though I'm sure if I was given some time, I could come up with more.
