Habbo Hotel

Habbo Hotel is a service where you can meet other Habbo Hotel inhabitants and chat with them. The service provides an Hotel with private and common rooms as chat setting. Before entering this ‘world’ the user has to create it’s avatar, a Habbo. The user can dress his Habbo as he likes. Each user can create one or multiple rooms. The user has to buy his furniture with credits. Through a SMS-service the user can buy credits. Each private room can act as a two-person chat room, whereas the common rooms act as groups chats. By moving his cursor over the room the user can be move, sit next to someone, go to the next room etc. The user has some gestures (wave, dance) and can exchange items.

It reminds me of a 2D-world some 6 years ago. I think it was called Alphaworld. At the moment this seems to be a very general chat environment with few dedicated topic, which you see in the chats that evolve.
