Never mind Steam workshop will be mega-cucked
Yea, what did you expect? Stalker isn't condusive to have a modlist, stacking mods is going to break your stalker install, if they allowed people to change configs retards would install 2 mods and completely break their game, then go cry and bawl to the support team. It's less of a inability to being able to make mods, and more of peace of mind, because after needing to help people install and troubleshoot mods for over a decade you realise drag and dropping files and basic troubleshooting is a step too far for the common human mind.

The world has been mindfucked by modlists, download now buttons and mod loaders, it's so genuinely fucked.
The good news is that now you can profile people for being gatekpt, if he has mods subscribed in his steam workshop, that means he's cattle.
So what's "upgraded" exactly?
Everything in the Legends of the Zone update for consoles, plus upscaled textures, trophies and achivements, gamepad support, select graphical improvements to renderers, changed UI, QOL fixes, and bug fixes.
This is what I read on the FAQ, what you can expect is a update to console versions of Legends of the Zone, now on PC with options for you to play with, meaning, they have a botched x64 engine conversion that Mataboo shoe-horned in along with it.
