Nostalgia... Lego was amazing decades ago so we want it to remain so. It's not anymore though. The whole raison d'etre, namely infinitely recomposable bricks to be creative, was lost the moment they realized they were a LOT more money in custom sets. Sets become collectible, perishable, trends can form, secondary markets exists, etc. It's simply about the baseline, not the principle. Sorry.

Lego sets aimed at children are still good! They work as standalone toys, and can also be reassembled, modified and combined. Very few toys are like this. Adults collect them, true, but there are whole lines dedicated to them.

My kids got a Minecraft set and just use the Warden as a toy and build with all the other bricks and a mat to put the poor lego characters in bad situations where they’ve woken the Warden up (he’s a strong enemy in Minecraft)

Lego is one of those companies that is simultaneously amazing and kind of sucks. On one hand the core product is incredible. The tolerances on the bricks are micrometer-level precision and the fact that pieces from the 70s snap perfectly into ones made today is mind blowing. On the other hand, a lot what the company does today just sucks. Set prices are outrageous. Printed bricks get replaced with stickers and many s…

The decline of technic sets is such a shame. There's so little support for anything but representative models of specific cars, despite the platform being able to support a ton of mechanical creativity.

I recently built the NES and Game Boy sets and thought both of those were really great. The NES is probably not priced for most people (we try to stay under 10¢ a brick), but the level of detail, whimsy, and mechanics are all really well done. There are hidden scenes and Easter eggs built into the system that are revealed as you build rather than highlighted as features on the box. I was genuinely surprised and had a…

The Game Boy is apparently one of the best sets of 2025, cleverly built and a nice display item. Still, it is for adults, kids have tons of other sets to choose from.

I often look at these and think they’d be fun for me to display, then think I’d prefer an actual Game Boy disassembled as a piece of wall art [0]. This sort of stuff is just so cool in my opinion.

Edit: now that I look on EBay building my own display like that would probably cost maybe $60 vs $189? Broken Game Boys are $40 on eBay, so maybe a project I could do for fun!

You can also only get so creative with lego. At the end of the day roblox/minecraft and video games trains kids to build more "relevant" things. Apart from tactility, I don't see what technic/mindstorm offers over digital.

Lego was always expensive, you can compare prices adjusted for inflation. For example, the 1979 Galaxy Explorer https://brickset.com/sets/497-1 > was around $32, that's $144 today. The reimagined set from 2023 https://brickset.com/sets/10497-1 > was sold at $99, $106 today. Not only it is cheaper, but much larger and with many more pieces.

Yes, they have kept up with inflation, and that is the problem. Manufactured goods like Lego bricks should fall in price through innovation in processes, scale, etc. What does raise higher than the average inflation should be be labor-intensive products/services. In other words, it feels much stranger today how expensive Legos are compared to 47 years ago.

In terms of creativity of model options, the Chinese compatibles are stomping them.

You can even get a model of post-explosion Chernobyl. Not to mention all the sci-fi tie in from Star Trek to Warhammer that real Lego hasn't signed contracts for. But if you want an 60cm Gloriana class, there it is.

Plus Technics-ish sets and bulk boxes that aren't 75% special body panels that only fit that specific model, since Technics itself mostly seems to have been downgraded to the automotive brands advertising department.

Part of the problem is a solid 1/3 or more of Walmart's LEGO aisle is now various flowers - https://www.walmart.com/brand/lego/botanicals/10056123

These aren't being bought by kids and if the entire market becomes nostalgic adults, eventually they all die.

You can still buy “generic” lego sets if you want. Look for “Lego Classic” sets.

They're a bit too simplistic though. Some of the classic 80s themes, like Space and Castle, primarily used regular bricks of reasonable sizes in a very limited palette of colours, with a few special parts unique to the theme. They were much more suited to taking apart and building your own creations. These days, there's just too many specialised and small parts, and too many colours. Even if you buy a big grey Star W…

If you like City, Lego has you covered, even now (cue the old jokes about Lego City having 500 police stations, 400 fire stations, 20 gas stations, and no shops and no houses).

The other themes of old have been replaced by movie tie-ins, and it's hard to build a pirate world out of Pirates of the Caribbean sets

We use a Lego phantom[0] to control for geometric distortions in a few of our MRI studies. The tolerances are so tight that it works really well. Especially important in multi-site studies. [0] https://en.wikipedia.org/wiki/Imaging_phantom

Really cool trivia, thanks for sharing :D
