I do like the touchscreen aiming (I just use my thumb), but there are still other problems. Since the touchscreen is meant for the stylus, nobody uses the right-side buttons for anything, so actions are on the screen too, and it can get messy. The D-Pad is not great for movement either (partially solved on 3DS), and lack of texture filtering abilities make 3D graphics look blocky. I think it’s safe to say the system isn’t made for this kind of games.
