What other games are there that use an art style similar to Another World (Out of This World)? The only other ones I know is Flashback and Prince of Persia somewhat.

I'm trying to figure out what to call this art style. It reminds me of tissue paper collage. Is this the same kind of thing in your opinion?

These games use a technique called rotoscoping, which is animating over live footage.

Since you can use different styles of animation for this, results may vary, but it's a good place to start.
