Land in the game is divided up into Islands, the Islands are set from the Linden Labs owned Mainland, to the private Islands that sit apart from the mainland collection of islands. A island on SL is more commonly known as 'a Sim'. Almost anything can be found in second life from shopping to dance clubs, to cyber sex, and even roleplaying sims.
