There's been tons of fun games about Lego, no doubt about it. But every game has always been the theme of Lego overlaid on another. Such as Lego Racing; you build a car to race with. Also, the actual environment/background is not made of Lego. The purpose is to race a car, and the building of the car is a facet of the game. The same is true for... any of them,really. Lego Marvel Superheroes, Star Wars, Batman, Indiana Jones, Pirates of the Caribbean, Marvel Superheroes, DC Supervillians, Lord of the Rings... etc. It's a world with a 'skin' on Lego thrown on top. (Not that it's not lovely)

LEGO Bricktales is absurdly fun and very intuitive controls (I actually play one-handed!), but horribly controlled with a controller.
