Top Ten Video Games that Started as Other Games

Here's a interesting little list from the folks at Machinima of games that started out as other games. The most famous example from their list is probably Super Mario Bros II. The interesting fact about that one that they left out is that eventually the game we knew as Super Mario Bros II (which as they mentioned was a reskinned Doki Doki Panic because the real Super Mario Bros II was too difficult for an american audience) was eventually ported BACK to Japan as Super Mario Bros USA.

I'm guessing that didn't do anything to squash the idea that Americans were terrible at video games.
