Oz World is a virtual world social MMORPG with an emphasis on meeting others as well as dating. Players collaborate on fishing, can build their own in-game homes, get married, and participate in various social activities. There is also a personals component.
Oz World doesn't really feature any combat or quests that don't focus on fishing or collaboration, but there are in-game events and tons of customization options for those who want a casual relaxing MMO space. There's an item shop for extras.
