I keep telling clients that much as I love Second Life it isn't the only world in town, and they need to chose the most appropriate world for each project.
As an example NSPCC has set up in Habbo Hotel, a long standing isometric teen virtual world. Habbo Hotel UK now attracts 750,000 unique users each month, aged 11-18. There are localised Habbo communities in 29 countries. The company behind Habbo said that as of December 2006 more than 66 million Habbos have been created around the world.
