Played Starcraft all the way up through the human campaign. That game is hard as fucking hell, but once you are used to the graphics (they sucked at first, but then I got used to them), it's mind blowing at how good of a game they made back in 1997. The game is still mindnumblingly hard, to the point of me quitting after the human campaign.
I had never even touched the game until this point in time!
