"Hopsiah the Kanga-Jew"... priceless. ^_^

The Half-Life one, at 48 min with all cutscenes included, is incredible! I particularly love the snark-jumps and using the scientists to prop open doors that are supposed to shut.

There's a 17 minute Fallout 2 one, but I haven't watched it yet. The Mario 64 vid is cool, too; all 70 stars!
