I saw Sylestia mentioned a couple of times in the thread. I'd personally advise against playing it, since some of the assets are AI generated.

Other than PCE, the site I'm most active on is Flight Rising.
I also check BeastKeeper now and then. It's got a neat genetics system, and it's pretty chill since your pets only need to eat on days that you log in. Unfortunately, the playerbase is super tiny, which makes buying things a bit of a pain, but I think it's possible to get anything you need from exploring, including premium items with a low chance, which is nice. Getting pets from the pound is definitely something you should do if you play, since you can get pets bred to have great genes and stat boosts
