Double Dragon needs to be remade, and soon. I know we got Double Dragon Advance, but a true next-gen beat-em up with HD graphics would be amazing. It could be hybrid 2D and 3D stages, have an 80's-inspired videogame soundtrack. Add in a few special moves, and you could have a classic on your hands.
Much like Pac-Man Championship Edition, this could bring back great memories and give us a brand-new game to enjoy.
