I have to agree. I wish they had gone more in a Stalker-ish way when designing the game, instead of this Disney-ish tone. I mean, I absolutely love this game, but I just personally prefer the ominous atmosphere from the Stalker apocalypse more.
I do love the weapons, the world, the characters, the quests and all the little details though. Right now I'd rate it 9/10. I really hope Obsidian keeps this level of quality up for their upcoming projects.
