Well Gearrs of war is a good game, and so is Gears of Wars 2. But seriously in flash it would just be too big to be a good game. What I mean is it would have to be like 100+mb to have great graphics, and great transitions with the guns, and motions. You would also probably have to have a good computer with a graphics card that isn't standard.
So yes, the idea is great, but it wouldn't be reasonable.
