I'm not a gamer, I play Tetris on my DS once or twice a year max, I just found this video (it's PC, BTW) and I've been watching the playthrough ALL day.  And it's kinda funky b/c I had been thinking not too long ago of drawing Mario in all these various other video games, and lo and behold not only did someone else do that but it's playable!

I used to play video games as a kid but I was never particularly good (I only ever beat Wario on Game Boy, though I think I came close to Mario Bros 2 on GB).  So these are really taking me back to my childhood.
