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.
On "the actual
environment/background is not made of Lego" complaint:
while Bricktales looks neat, its "environment/background" is tiny.
For anyone interested in a more Minecraft+LEGO experience, with an actual world made entirely of LEGO that you can interact with, check out LEGO Worlds. (currently 80% off on steam)
I'll attest that Lego Worlds is probably what someone wants when they want an entire interactable Lego world to play with, but I wish they had spent more time cooking with the game.
The parts list is tiny compared to what actually exists, you can only rotate on the x axis, and you can't make your own vehicles or decorations; you have to rely on what's already in the game, which is a lot, but still.
