Sometimes I wonder why simple things like Guitar Hero and stuff appeared just in this generation. You know it is so simple. Now in Brazil you can even find this for Mega Drive (Genesis). Pretty curious indeed. But have you imagined something like Super Smash Bros on GameBoy? Yeah...pretty weird stuff I know. The technology mimimis and all kind of barriers of hardware. So fuck you all. See this video below and stop thinking that you need technology to do stuff.
It is called Super Smash Land and have the same mechanical as Battle Arena Toshinden (バトルアリーナ闘神伝) but designed to meet the SmashBros gameplay. Pretty cool uh? You can download a demo of Super Smash Land to run on your PC [here]. The game is being crafted by Piki Geek.
