Old age ?... ;)

Very well possible.

I'm still having the issue where most of the time now it seems, the IN LIBRARY label is not showing up for me.

That of course impacts me, because I am not going to visit every game link to see if I own the game or DLC. My memory isn't too bad, but I have over 2100 entries in my GOG library now, so with all the different versions of a game sometimes and the occasional rename, it is impossible to stay on top of it all.

I am guessing it is a PC memory issue and the order elements are being loaded now. If you look at the source code of any GOG web page, it is ridiculous the number of scripts that run ... talk about web page bloat.

Whoever does the GOG web pages, needs to do a course on KEEP IT SIMPLE.

Sorry. I'm somewhat allergic to changing things just for the sake of it :P
Best example: The windows start menu, which was already perfect in Win95...

The new search bar at the top is really annoying & intrusive.

And so too are the pop-ups that appear when one hovers the cursor over a game whilst browsing the main GOG store page.

Both of these "features" make the store worse & aggravating to browse.

Please remove them and revert the store back to how it used to be before these horrible changes were implemented. It was much better without them, and it's much worse with them.

I sometimes wonder who did more damage to the global economy in recent years. The Pandemic or overeager UI designers...

Yeah. I really can't recall any website or GUI application that improved it's UI in the last decades. Everything gets useless tiles. Everything gets useless popup menus. Everything gets bigger with less information per area and scrolling galore. It's depressing.

I always feel like most sites eitehr started out, or relatively quickly settled on an optimal layout, but they ccouldn't just let it stay that way, things need to constantly be updated and redesigned anyway. Changes for the sake of changes. So we get the proverbial fixing of things that aren't broken, and the sucky results that follow.

Ok, I'm not sure if I'm just imagining this, but...it seems to me as if these categories were less "massive" before, no?

Is this a new design?
Or am I losing it?

If you ever look under the hood (at the source) you will see all sorts of crap going on, unnecessary crap to my mind for the most part. But maybe it is security through obscurity due to the massive amount of CSS and scripting etc.

I really pine for the simple days of web page development, instead of the current bloat that so many sites have now. In reality it is an abuse of our PCs and devices.

How it is decently maintained I have no idea, as personally I would consider it a nightmare to do, especially if something goes wrong, and there is so much to go wrong.

It seems to me that many web developers are either on some ego trip these days, trying to be clever for the sake of being clever, or just use WYSIWYG software that increases the bloat many fold, quite unnecessarily.

Developers may use frameworks and tools such as angular, Sass, Less which get translated to html, css. The original source code may be very clean and maintainable, but the result of translation which is meant for the browser, may be judged by humans to look like crap.

But, but... PROGRESS!!!!!!!!!!!1111111111111elfeins

Yep, noticed that too. Same wasted space trend as everywhere.
Yep...

Lots of added information, though, immediately visible without needing to hover for a game card. I love seeing platform information right away. And on the main store page, too!

A little less whitespace would be better (information density ++), but overall I consider this a massive improvement!

Oh, I agree - the plus on information is nice.
But as you say: it could have been served in condensed form - while still being equally informative.
