Earlier this month we told you about Mari0, a Super Mario Bros. and Portal hybrid from indie game developer Stabyourself.net. Yup, it's the old Super Mario Bros. with portal guns, user created content, a map editor, and four player local co-op. It's exactly what it sounds like. I downloaded the game here and took it for a spin. I have to say, it's a pretty good time, especially for a free download. The portals worked well and it's saturated with nostalgia.  

Community group known as Stabyourself.net has finally accomplished a gamer’s dream: taking two awesome games by two legendary publishers, Nintendo and Valve, and put them into one, stellar game.

De-makes (2D or retro-style conversions of more recent games) are nothing terribly new, but adding elements of your favorite current-gen games to a classic platformer can turn up similarly awesome results.
