Hello! Always nice to see new people taking an interest in wq3. As you may have guessed, the number of players is not very high these days. But we are hoping that some new maps, and our upcoming patch, will get us some attention. Yesterday I counted nine or ten people playing at the same time, on three different servers. That's pretty encouraging, but unfortunately a rare sight these days.
You can see a live server list at this url:
http://www.bootblock.de/wq3/It's also got statistics that will give you an idea how much traffic there is. If you join a server, there's a good chance that I or some other regular will join after a few minutes. It seems there is often someone keeping an eye on the server list. There is also a wq3 filter in ASE, if you use that.
