I mean really instead of complaining about there being no good servers, make your own good server. Create something new and fun and different and be the change you want to see.
The only reason people don't keep up their servers for very long is because of Tezuni's server.
Maybe once or twice you'll see a server surpass Tezuni's in the playercount, but that's pretty rare (And those servers don't usually stay up for long or they get boring fast).
People think that they can make a stuff server and be just like tezuni and get a ton of players, but that's never true.
I don't know why people go on Tezuni's, and to be honest, Nobody really knows.
