Okay, this one is going to sound weird, but I want a sequel to the original Donkey Kong. Before Bowser kidnapped Mario’s girl, a barrel-throwing ape kept her hostage. Since Donkey Kong, there hasn’t been a Mario-Kong game where Mario is the protagonist and DK is the antagonist. In fact, since the original Donkey Kong, the ape was a good guy (even in the actual DK sequel “Donkey Kong Jr”). I want to see him as the villain once again.
I don’t know what kind of game it should be, but a sequel to the premise of the original Donkey Kong would be awesome…at least, to me.
