I forgot they just remade one of the Cossacks games. It's not really relevant to me, though, or most people.
My understanding is the team split into new dev studios. So what's remaining of the talent that made the stalker games, I really don't know. I doubt they could recreate those games today in the form of a sequel.
I know about
Survarium but I have no interest in online play. I know there was another one but I can't recall the name, and they were using a bunch of content from Stalker which brought them a lot of negative attention and looked incredibly sketchy.
I'm just updating Survarium. I don't think I bothered with it in 2016. Might be interesting to see what they've done with it.
Found what the other one was: Areal. Rock Paper Shotgun followed it pretty closely when this was all going on.
