To give players an early taste of the Source engine first hand, Valve releases Counter-Strike: Source. In the months leading up to Half-Life 2’s release, thousands of players enjoy the thrills of realistically knocking over barrels and shooting up fruits and vegetables and other small props. For reasons unknown, Counter Strike: Source never takes over Counter Strike 1.6 in terms of popularity. It is also at this time that the full extent of Steam is unveiled, in particular that it will be required to play Half-Life 2 and all other Valve titles from this point on. Some gamers are so incensed that they vow never to buy a Valve product again, no matter how good it is.
