Meez.com. it's a website where you can create an avatar, chat with friends, and play games too.
www.Weeworld.com is very fun try it.
There is a webstite that has avatar people. But I don't think you have to download it.
Gaia online is one...

The PSP games must be. The PS Vita games also are available without download
You need a PSN account before you can download games from the PSN.
I have not found any. There are free adult games that you don't have to download but the free virtual worlds just aren't out there for adults yet witch is a real bummer cause we all know they have them for kids.
