I know it probably won't happen but I think it would be an awesome concept!
Imagine flicking the controller to throw pokeballs. Awesome.
Using the battle environment to your advantage or against your opponent. Awesome.
Amazing graphics and still have accessibility to wifi. Less nostalgic, but awesome.
These are just some of the possibilities I thought of if Nintendo did ever develop a main series Pokemon game for the Wii. What do you guys think!?
