Catskills. IMHO the game went downhill with the T2A release in 1998, and then was completely ruined by the time Renaissance came out in 2000 (although I had already quit well before then).

It's a shame because I feel like the gameplay was kind of already destroyed by the time the servers were relatively stable and bug free, so it feels like it never really lived up to its potential. But during the few hours a day when it actually worked properly, damn.

Catskills had the best roleplaying community I've ever seen. I miss it.

I also had so much fun on Siege Perilous when it was those color wars with the 4 castles. I can't believe they ever changed that.
