I'm not a fan of single player games, and even less so of large open worlds. But in this game, the world absorbed me so much that I didn't even notice when the 100 hours had passed.
At the moment (over a week after the premiere) the game still has a lot of bugs and there are many things missing, that were in the previous Stalker games. Despite this, the atmosphere, the variety of quests and the many possibilities of playing them in other ways overshadow all the inadequacies.
In a year or two with mods or updates from the developers I will be able to recommend it to anyone, with a clear conscience.
For now, it's a great game for fans of FPS games and post-apocalyptic atmosphere.
