Actually, I had been thinking of suggesting a similar thing too.
Graal is a powerful creation tool and can be used to make a multitude of game-styles.
Then again, I've always been interested in that whole game-creation thing.

And for anyone that thinks Graal wouldn't be fun offline, keep in mind that it was based off of Zelda, which is, of course, a single player game. =P

Anyway, if it does happen, there should be some way to distribute things as a level pack, that can be selected from an in-game menu. Maybe password protection on the levels as well, so people can't just open them and edit them to cheat?
