Hi — I run EasyHub, an ad-supported HTML5 / Unity WebGL browser-game portal. We did not make the individual games; we host free-to-play web titles.
Not an adventure, so Other Games seemed the right room. One management/sim example we have on the US pages:

Curious if anyone here still plays short browser sims, or if this is too far from the adventure beat. Happy to take feedback on the portal itself (contact@easyhub.games).

Not for long, but I played World of Claudecraft in my browser.

I still think browser games have a place, especially for something you can jump into for 10 or 15 minutes without installing anything. I probably wouldn’t use them for a long serious game, but for short sims and time-killers the format still makes a lot of sense.
