So, I'm finally running through S.T.A.L.K.E.R. 2. I played a bit at launch but took a break to allow for some patches.
I knew from back then that I shouldn't expect roaming packs of stuff or persistent NPC AI across the map. Fine. Got ambushed by a lot of random Military, I bore witness to random Bandits getting wiped by a huge gang of Snorks with both having spawned directly behind a truck garage - it was really funny to watch, though, not as funny to mop up the dozen Snorks...
But the thing which stung the most happened just now. I've been cutting the South-Western corner of The Cage at the Cement Plant to get to the region's South-Eastern corner to explore it. I knew I had the Machine Tractor Station at my 2 o'clock, and that's where the aforementioned Snork bonanza occurred, after it greeted me with 6 Bandits and two Bloodsuckers when I first got there.
As I exited the building site perimeter, I ran into a group of Loners coming from the South-ish. My mind instantly thought: "oh, that means the Tractor Station's clear, otherwise these peeps would've been loot fodder for the return trip." And I immediately realised that, no, it only means that they may have spawned behind the perimeter wall, out of my sight line.
And now I have to sneak through a ditch because I don't want more Bloodsuckers.
Update: decided to double-back through the Tractor Station when returning to the Factory (no way I'm going in a train depot with a Seva-D, thanks!), and, of course, killed 6 Bandits, got my ass chased away by two Bloodsuckers as I finished looting, which were ambushed by a dozen Snorks as I was booking it toward The Cage. Of course!
I swear, there's nothing more cathartic than having an ugly-sob session brought on by some of the vistas in DS3, or by seeing the slowly growing family of lost souls in Majula. And that first time you realise just how (needlessly) wrecked the world is in the first one... *chef's kiss, exquisite suffering!
I still don't understand how a game can empathise that well with despondency, but it absolutely does. All of them do, but the Dark Souls installments especially.
