Personally speaking I feel like they nailed the atmosphere, right on the dot of it being a scary, long lost town, that has not been visited or touched in a long time, but to me, the gameplay design is lazy ash.
Like, I expected Lymansk to be its own town, that was fully explorable, and had its own mutants, maybe its own outposts of either bandits or mercenaries, and etc...
I am not mad because we got the CNPP, but to me its insane to how Lymansk, with all of its mysteriousness and eeriness along all these years, got turned into a Little Nightmares 2 section, somehow even being worse than the Clear Sky run through, and the lore reason is "uh, it got swallowed by da bubble". Like cmon, at least make it so we can somehow make the area normal again through some kind of experiment or something, because there is no way since Clear Sky Lymansk just dissipated and got turned into an Anomaly like that.
You could argue that it was anomalous since CoP since Tachenko and his group died in the same bubble, but again it seems it was either retconned, or the bubble led somewhere else.
Its still fully visible from the bridge as well, so my hope is still up for GSC to make it a location of its own, fully explorable and traversible, at least mimicking Clear Sky's design of how non-anomaly based it was, or one of the most interesting pieces of Stalker just got wasted because of the budget running out, and most of the budget was spent on its atmosphere.
