A lot of us that have been playing this game for more than a half a decade and have witnessed the ups and downs of the game and community and after reminscing with some people about my own favorite times and periods of Tremulous, I'm interested in what your guys' personal glory days and favorite memories of the game are.
NT, Zilla, Pk (mostly inactive), OPP, EBSF, and whatever Sonic's clan was at the time were all around during my time in AA and the public games on AA were always full and had some of the best players of all time constantly playing. The scrims were always there whenever you got on and they were always exciting (except when playing OPP lol) and ultra competitive and the competitiveness of the game is the only thing that ever really motivated me to play.
A close 2nd for me is the GPP Summer Olympics. The bad blood and shit talking between the top clans made it the most competitive and successful tournament in Tremulous. It brought back players and old friends that haven't touched the game in years and the tournament made people want to get better and the drama made the game fun again.
