I want to see 3D overworlds with the camera pointing at the same angle as Animal Crossing: WW fashion (without the whole "curvature of the earth" thing, of course). All objects on the map (People, items, signs, etc.) should be sprite based. I also want to see lighting effects as well, like if you're in a jungle, some beams of light could break through the trees.
For battle scenes, sprites on a detailed BG (no circles of land like the advance games), with all attacks being 3D. The trainer should also be a 2D sprite with a more fluid throwing animation.
