Used to play CS1.6 for 30-40 hours a week in a DFW-based server called A Better Place to Play. Every time as_oilrig showed up in the rotation, people would scramble to join me on the CTs. We had so many great strategies, we could win almost every round. (And mind you this was a 32-person pub.) Greatest of times, and only possible because the server had a dedicated community and our clan was meticulous.

Also there were some killer WC3 mod servers out there. My goodness the fun that was had....
