On the DS, games used both screens for the gameplay. In both Zelda games on the DS, the bottom screen was used to move around with the touch screen. I doubt Nintendo would want to make a game like that for the 3DS, because that would mean pretty much all of the main gameplay would be in 2D. Do you think Nintendo would be willing to use the bottom screen for the main gameplay? I haven't actually seen much of current 3DS games, but from what I've seen, the bottom screen now seems to be just for menus, maps, extra buttons, and things like that. I'd be willing to sacrifice 3D for touch screen gameplay, but would Nintendo want to do this in a system where the 3D is such a big feature? 3D is in the system's name! Just a thought I had. What do you think?
