Didn't see a thread here, so here goes:
Observer is a walking sim where your choices don't matter. That said, the atmosphere and world building is top-notch. Much of the storyline is predictable, although the endings (player has choice of one out of two endings) capped the experience for me and lifted the overall experience significantly.
Has anyone played this game? Thoughts? I think it makes a good Halloween game. The whole thing is over in about 4-5 hours.
