This video, by Antonio Palmucci is pretty great, in a throwback, Mario 64 kind of way. We've got the classic "Mario in a maze" setup with old school 3D graphics, trying to outrun and find a way to take down an appropriately giant Bowser, while Pacman is rolling around in there as well there, causing problems and starting shit. There seems to be no real alliances in the video, with the three heavyweights involved in some kind of fire breathing, chomping, flip-jumping free for all. It's good.
Check out the video below, and if you like it, Palmucci has a ton more to offer on his channel, which you can find here.
Give the man a like, he's done some good work.
