Sometimes, you just gotta know when to give.  Project Spark launched late last year to decidedly little fanfare, perhaps partially due to its free-to-play model.  Despite Microsoft's offer to allow players a chance at creating their very own worlds and tales, the game never quite got a foothold in that creative space.

Project Spark is a mad scientist's dream. The game is one part creative playground, one part game designing tool that uses a simple interface to let you shape a world from the ground up. Better still, you get to add behaviors to creatures in the environments, building a living worlds you can share with other players.
