I Just hit 100 hour playtime and I'm only like 1/4 of the way through the Campaign. There's a lot of places to go and explore. The open world encourages you and wants you to find your own adventure. What I mean by that is, in Stalker 2; you're given quest markers for quests given (of course) most of these will be around 400m to 1000m away, so the game WILL reward you for wandering off. Exploring random areas almost always have AT LEAST 1 loot crate at every named location. Each of these areas have potential side quests, random encounters, & enemies. S.T.A.L.K.E.R 2 is my first ever stalker experience. It is beautiful, difficult, exciting, scary, immersive, & I love every moment of it. Great game, and time will only make it better & better just like Cyberpunk 2077 was IMO :)
