A game that defined competitive gameplay for more that 10 years, Counter Strike still is amazing for Valve even remaking the game into an updated,more graphical, and even more guns ( Counter-Strike : Global Offensive). With the source engine the game is more enjoyable with a better physics engine. Valve once again takes the cake with this predefined game played by millions today.
