It's a people problem, has been always will be. Remember the Devs are people too. They've made a pretty amazing game for a couple dudes in a basement.
In my mind, the problems are two fold. On the one hand there hasn't been any new content added to the game (sorry, re-working gamma isn't new) in years, and the low player population. When I came back a year ago to the game, it was pretty much the exact same situation as now except STC and friends owned everything. The only difference then was that there were gamma islands with thousands of turrets to protect them. That's the biggest difference a year makes, besides who is top dog on the server.
As far as the players though you're right, the community has been pretty horrible to each other, and I'll admit that I've been one of the biggest contributors to that. The only way we can fix this issue is step by step, but we can start now.
I officially pledge to keep the trolling, insults and derogatory language to as much a minimum as I am capable, and ask that all vets join me in this. It's time to put aside our differences and work toward a better future within Perpetuum. The past is the past, and let's leave it there.
