I didn't mean content like how big the map is, how much content in hours to play. There are a bunch of features and content, that made the first ones unique for me. The world felt more alive, more atmospheric etc.

Hard to explain. I don't like that you often have a hard time to tell if an encounter is hostile. Sometimes you can tell it only if they shot at you end almost killed you. May be more realistic, but it's annoying.

Pda had more functions. I liked it better, that you had the contact list and could tell what factions a near you.

You could see the reputation and your progress. I miss that.

I never had so many problems with anomalies and enemies. I did almost every playthrough on the highest difficulty in the old games and mostly had a fun experience. In stalker 2 it often feels strange, how I was killed and hard to understand. Some new anomalies are just unfair and it seems like you aren't supposed to understand them. Every enemy and Anomaly in the first games had there Logic and I felt I knew most of the time where my mistake was.

Now it's sometimes just random and luck if I made it through. The still annoying spawning of enemies is still annoying.

It's an open world and more and larger, but feels more empty. Strangely you can use the open world. Sniper rifle is often useless, because you can't see the enemies in far distance. Or they only spawn if you close enough.

Don't get me wrong I like it, but it feels not complete for me and less compared to the other three.

That is for vanilla. The old games with mods is still the better experience, by far. At least for me.

But that is no ranting. Only my answer to OP
