Communist Propoganda video featureing the hero of the people: Mario.

This is the slowest playthrough of SMB Level 1 that I have ever watched, and is a record that does not need to be broken.

Watch as freak-show illustrations of Mario World characters accompany an extra bizarre japanese musical rendition of the game's theme song.  Who knew princess peach was such a bitch?

This mod for Unreal Tournament 3 looks fantastic and makes me want to get a copy of the game.  The 2d gameplay is inspired.  With a little poish, this could be one of the most interesting game mods I have ever seen.

There have been many videos online of people performing the super mario brothers theme song in interesting ways, but this has to be the most original I have seen so far.

This article and accompanying video are awesome. From the article: "But, we can kind of think of the multi-playthrough Kaizo Mario World video as a silly, sci-fi style demonstration of the Quantum Suicide experiment. At each moment of the playthrough there’s a lot of different things Mario could have done, and almost all of them lead to horrible death. The anthropic principle, in the form of the emulator’s save/restore feature, postselects for the possibilities where Mario actually survives and ensures that although a lot of possible paths have to get discarded, the camera remains fixed on the one path where after one minute and fifty-six seconds some observer still exists."

This is one of many videos on youTube of Syobon, the Evil Super Mario Brothers clone, which appears to have been built by a Japanese 2chan-er. This game is brilliant in its abuse of the built in gaming instincts many people have with regards to the classic super Mario Brothers game.
