7. Firewatch
From one game that hardly anyone will clock without outside help, to another that simply drops you into the shoes of everyman Henry, and asks you to figure out precisely why he's decided to take a job in the middle of the Wyoming wilderness. Granted, in one of the most affecting scenarios I've played in quite some time, you'll find out the core reason to his isolation almost immediately, but it's everything that comes afterwards that'll grab you and not let go. Put simply, Firewatch is not what you think - it's not an idyllic, free-roaming, lighthearted take on America's apple pie ideology; instead, by forming a relationship with fellow fire-watcher Delilah (one that you dictate in numerous ways), there's a dark mystery that unfurls the more you play. Like 2013's Gone Home or last year's Everybody's Gone to the Rapture, Firewatch is best played knowing only the basic foundational elements of its narrative setup. Its visuals are absolutely outstanding (having been worked on by legendary artist Olly Moss), its overall story should (in theory) impact everybody differently, and regardless of how much you like the final wrap-up, Firewatch provides an extremely mature and unique take on some rarely discussed subject matters that any gamer should be happy to have in their collection.
