Source Engine SDK Released
wolrahnaes writes "It's finally available to the public. According to a post on The Valve ERC Collective, the tools needed to create maps and mods for Half-Life 2, Counter-Strike: Source, and other Source engine based titles are now available on Steam. Some documentation is available here."
I disagree
the original Half Life was amazing and would of been remembered as a classic without mods
what mods have done is made it stay popular to this day rather than just being remembered
