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.

There is no world like Onverse. All virtual worlds out there are unique in their kind. About downloading, you shouldn't worry. Make sure the world you want to play is safe. Onverse.com is completely safe.

Onverse is a virtual world game that you have to download to play. It is free to play with the option of spending money for perks such as VIP and Cash Coins. The download takes about 5-10 minutes on a PC or laptop with decent internet connection.
