Yup, some bright spark is planning on making the possibilities that the Mario With A Portal Gun video joked about into a fully fledged playable reality! Its named Mari0 and is currently being developed for Windows, Linux and OSX by the two man team ‘Stab Yourself’. The game will contain all of the original Super Mario Bros. levels as well as all of The Lost Levels. Downloadable map packs, a level editor and even co-op are also in the works. Lets hope Nintendo play nice long enough for this game to actually see release in some form!
