This game gives you emotions other games do not. Also its progression mechanics are wonderful. You literally can go from a nobody to a literal god if you learn (Knowledge is power). The emotions I got: "Oh you think you're hot stuff? You just blew up a barrel hidden inside snow and now you're dead." "Nice run you have going over there. Would be a real shame if a pixel of Polymorphine would randomly touch you". Seriously. Best single player game I had in a while. Defintely a gem to add to your collection if you like modifying your arsenal and tinkering your strategies.
