Metro is a very, very solid fps and tells a decent story. It fits into the "BioShock" genre as I refer to it: fps, sci-fi like setting, story driven and some scrounging. Each game runs maybe 10-12 hours if I'm recalling right it's been a few months. I played the first on the easier setting while I played the second on the harder one(accidentally). Stealth is not forced but I recommend that you try to be sneaky some of the time to conserve supplies. There will be a jump scare here and there but nothing too frightening. And there are a few dlc with Last Light that are self contained stories for the most part. They were also pretty good. Overall pretty great game and that is a price you can't beat. Though I am a little bummed out the next game will supposedly be open world.
