From StrategyInformer.com: "In November 2008 A Kingdom for Keflings became the first title on the Xbox 360 to allow gamers to bring their avatar into a game as a fully playable character. Following suit, the game's developer NinjaBee announced that the Keflings sequel, A World of Keflings, will become the first game to allow players bring their avatar's props into the game world.
"People put a lot of work into their avatars," said NinjaBee president Steve Taylor. "A Kingdom for Keflings is already a great place for that work to pay off, but A World of Keflings has even more extensive avatar support. One of the coolest examples being the ability to see players' props in the game."
