I play in the IDL ZDaemon CTF League and STA QW Draft TDM League which have small communities where everyone knows everyone else. You rarely see aliases on servers and we generally play organized pickup mix games to practice. Both leagues are doing fairly well, with the IDL lasting 11 seasons thus far, perhaps the longest id based game league in NA ever(?) and the STA propelling QW 4v4 TDM back to activity not seen in many years. I think it was 2005 or 2006 since I've seen two 4v4 TDM matches going on at once in North America servers. Yet I've seen two 4v4 TDM matches going on at once multiple times within the past few months due to the huge success of STA. If you want to play in a draft league in North America check these two leagues out. Also if you just ever wanted to try or get back to playing ZDaemon (Doom 2) or QW now is a great time.
