Playing Metro Last Light. I think I was one of the lucky ones who discovered the gem that is the original Metro 2033 and having played that makes this sequel that much more meaningful and engrossing. I just started it and the detail and gameplay is amazing.

One gripe is that the story follows canon from the novel as far as your decision whether or not to nuke the Dark Ones in the first game. It's understandable that they couldn't make two different games based on the decision you made in the previous game, but it does bother me just a little that the effort to get the good ending in the first game doesn't matter for the second game.
