I'm going to give this an upvote because mechanically it's a good game but I'll be honest with you, this is probably my least favorite in the entire STALKER series so far. I like a lot of the ideas going for it, mechanically it's pretty good but there are things about it that don't really mesh well with me. The locations aren't really interesting to me (the beginning area being my least favorite but having some of the best quests funny enough); the story to me is ok, not the best but not the worst; like I don't know. I've been told this is the best STALKER mechanically speaking and I see that but everything else? It didn't really do it for me to be honest and I'm sad about that. I wanted to like this game more than I did to be honest. I don't really know how to elaborate on it much other than that. I'll give it a thumbs up, I'm glad I played it but to be honest nothing will EVER beat the original, and I'm looking forward to playing STALKER 2 if it ever comes out. But I don't know if I really want to play this again much?

Pros:
Plays great
It's more STALKER
Beginning quests are more interesting
A lot of cool ideas (for example there's multiple endings and they're not all variations on the final choice or whatever)

Cons:
Story is ok
Locations aren't memorable
Further in the story goes the less interesting quests get (except the last quest of what I call act 2 and a cameo in the story that I won't spoil)
