Been wondering for a while. One of the largest complaints with iphone games is that virtual buttons/stick plainly suck. They aren't really all that responsive and they obscure a large portion of the screen. This made me wonder, why people make games 4:3 dimension and have borders on the side where the buttons/dpads are? That way your fingers won't be blocking the game screen. Sure it might look kinda dumb in screenshots but gameplay works way better. They do that in cave games and those control and play fantastic.
