I just wanted to share that ThatOneBonk is working on his own PSONE alternative called Thallium and they're planning to launch it with 2048 crossplay from the looks of it, so we should see HD/Fury for Vita and 2048 online campaign make a small comeback this year. I don't have any other details really but I'd stay tuned for any big news this year.
I do see people randomly pop in on rare occasion but they don't usually stick around long. Most the games I find are organized on Discord still. Just not enough people.
I'm sure if more people knew about PSONE there'd certainly be games open every hour of the day
