The Rise Of Counter-Strike
b0r1s writes "Business 2.0 is running a story about Minh Le, and his now famous Counter-Strike mod for Half Life. The article explains the origins and motivation for the development of the mod, as well as explains the virtues of making code freely available for those who wish to hack games."
Imagine the virtues if all code (not just for games) was made freely available to developers.
Then even Microsoft developers could freely use the development versions of software without the large cost overhead. That might spur on Windows development by the masses, just as has been done in the Linux and OpenSource realms.
