Firewatch is an enjoyable walking sim with fun characters, fantastic voice acting, gorgeous visuals, that doesn't stick the landing. The game is incredibly good at building up a mystery. You uncover more clues, you start getting paranoid wondering where this is going to go, begin caring for the other characters, hoping that they turn out okay, only for everything to come crashing down when you finally realize what it is. There was so much build up for no pay out.

That said, do I still recommend this game? Yes. Everything up until the last 10 minutes is fantastic, but be prepared that it may not satisfy a coherent story with an ending.
