Yes, exactly.
My son wants to BUY EVERYTHING, RIGHT NOW (which is also true in the stores of the real world, not coincidentally). But to unlock the minifigs and vehicles and the on-display minikit models, it requires a lot of puzzle solving, and the puzzles are not only commonly beyond the ability of children, they're beyond what they've previously shown is possible in the game. Lego Batman especially has some bizarre "wait, you can use that power on THOSE things?!" moments.
Combine that troubled logic in the gameplay with a 7-year-old who is bored of Daddy trying to figure out a puzzle, and it's pretty rough.
