Counter-Strike: Global Offensive took the long way to success. It started off with a number of significant flaws, but with time and some substantial patches, has become one of the most-played games on Steam and one of the best PC games you can play.
As usual, the people who know the game best are the ones who spend every night and most weekends in the trenches, defusing bombs, shooting chickens, and desperately hunting for knives. Also as usual, the people who love the game most are also the ones who have the most complicated relationship with it. Play a game enough, and even if you love it, part of you will probably start to loathe it. In a loving way. If that makes sense.
