You are right, Lego prices are one of the few, which didn’t go up as much as other popular toy brands, in fact for a few decades now they managed to be consistent with prices.

The audience is huge for SW and Lego amongst adults makes it possible to release these enormous multi-thousand piece sets, which pushes the prices up. More pieces = higher price.

Its a lots of money? Yes.

Is it more overpriced, than the average lego set price per piece in general? No.
