This seems like a really obvious thing. I'm fairly certain that it hasn't been done before. I mean, MOST popular characters have had sprites of them. Well, I guess pixels are used here. I don't see the difference. We're just getting out of sprites of course.
This does seem old by today's standards. It's just great to see video game characters rendered in a classic way like this. I've seen them in their regular forms so many times. I'd love to see a flash cartoon out of this. Better yet, a game.
