Went back to S.T.A.L.K.E.R. 2 now that about a year has passed and we're on the 1.6.1 patch to see how far the game has come and...well, they've added Night Vision Devices, and the Mosin, and it does run more stable, but other than that very little seems to have changed about the things I disliked.
In fact, one of my main complaints, enemy spawning, seems to have regressed since I last played, even at release with enemies obnoxiously spawning around you it'd take some effort to actually catch them "popping in", but on 1.6.1 I've literally had enemies pop into existence right in front of me on enough occasions that it's become rather bothersome.
There's also generally too many, it's literally impossible to get from A to B without the game spawning a bunch of enemies around you, if you're lucky they'll be too busy fighting each-other (which, I suppose, is an improvement over release where they'd all go for you). To test whether it was the game or I was just imagining things it I decided to make the trek from Quiet to Azimuth Station (after the mission that takes place there) multiple times in a row, this is a short distance that has you cross a tiny strip of empty bog, of the 8 times in a row I made the corssing (4 in each direction) I didn't run into anything only once, every other time there was something going on in this tiny strip of land. That's ridiculous, especially since there's no realistic way for anything to get there.
Missions still have the same issues they've always had with exposition but they've somehow managed to break in-world subtitles (which is a bit of an issue, seeing as I can't stand the English VO, but I also don't speak Ukrainian...) so I have to rely on memory for much of the context.
Haven't had any main missions outright break though, which is nice. Worst I had was an early side missions for the Ward in the Chemical Plant that I had to reload 6 or 7 times to get to function correctly.
So yeah...there's supposed to be an engine update in the next patch (1.7), honestly not sure what good it'll do unless it somehow also fixes the spawn issues.
