Ultima Ragnarok Online. A private MMORPG server that is operated by the one and only GM, CaptainMarvel. He has received large amount of income coming from player's donation, approximately 10000 dollars in 10 months. This server is nothing but to scam player's money and the owner will nerf anything to promote players to donate.
I hate uRO because the owner makes ridiculous password change fee and other sort of additional fees. So much for the server being "free".
