As most of you know Super Smash Bros Brawl came out recently for the Wii. Brawl was unuiqe in the sense that there were four different ways of playing the game, One of the controller schemes(Sideways Wiimote) proves that Smash bros can actually be played on the NES. And if you can smash on a nes, there is definantly a chance to smash on the DS. The control scheme would be sorta similar if anything better. Plus Nintendo WiFi Connection, a Smash Bros DS is an idea better than sliced bread.
