Counter-Strike: Source

"...Counter-Strike: Source is, once you've gained a knack for it, the most consistently rewarding and surprising team-based shoot-'em-up available on the PC today. It's been dressed up nicely for its relaunch in 2004, but it wasn't broken, and Valve hasn't fixed it. But then the developer hasn't finished it either. And that does take some of the shine off a project fuelled more or less entirely by the desire to polish."
