Check out the video below for Super Modern Mario Bros. It's a novel concept dreamed up by a gamer, removing a lot of the cutesy Mario-ness, dialing up the level of seriousness by removing the music and adding realistic sound effects. It’s a bit more violent, too, with Goombas exploding and Mario crashing to his untimely demise when he leaps towards the end-of-level flag and fails to successfully grab hold and slide down. Look, just watch it--it's way more fun than reading our description!
