that's the Nintendo Power effect.
people thought they were insane to show you exactly how to beat a game, yet it encouraged you to finish quicker so you could buy the new game.

Lego's version:
complicated
amazing-looking
expensive

all of those things encourage you to keep the set built and NOT "mess with it"

just buy more Lego
repeat

how many people buy two of the same set? one to "keep" and the other two use the torsos to make your own stuff? probably more than you'd think. now their tactic has sold two sets, as well!
