LEGO City/YMMV

And the Fandom Rejoiced: AFOLs were quite pleased by the introduction of highly detailed, model-like building kits a couple of years ago.
Crack is Cheaper: Building a reasonably equipped town, i.e. with all important buildings, has always been quite pricey. Said important buildings such as a police station or a fire station have always been among the biggest and therefore most expensive sets, older sets remain costly (beware if they include parts not found anywhere else), and what's your town worth if you haven't got a hospital yet? And now imagine that you're not an AWOL earning his own money but a kid relying on presents and pocket money.
Dork Age: Town Jr., from the late 90's. The sets were mind-boggingly simple to build, with buildings made of a few specialized "juniorized" parts, cars with single-piece chassis, printed-on headlights and no doors, and uninspired designs. Thankfully the juniorization has mostly stopped after Lego realized its mistakes.
Periphery Demographic: AFOLs. After all, it's them who can afford the really big and fancy sets.
They Changed It, Now It Sucks: The reaction of many AFOLs upon Lego's changing all its colors in the 21st century.
- Very old-school Lego fans (or former Lego fans and parents of Lego-playing kids) think this way about specialized parts.
