Nurien uses CryEngine (you may know Entropia and BlueMars use it) and offers a superreal virtual world. (See video below!). Members have their own profile page, enjoy chatting and games like a quiz show or a dance compettion.
Nurien plans to launch in China, Hong Kong this year. and do a USA release next year.
Cyworld, Korea's leading Social Networking Service which has 22 million members(!) in Korea, has launched a new 3D world called Mini Life in June.
kloseup is a online machinima making service. Select scenes, animations, and create movies. Adding that, you can upload google sketchup files.
I don't have much information about ZEB. I tried to visit the website again, but no response. The service is continuing?
