Second Life is a complex tool, with all sorts of nice options. To chat and listen to music, to explore different small worlds who enjoy it has its "Charr" shape to model worlds, who is also role play (not classic MMO / RPG but chat-based RPG), which takes place in SL certainly a lot of things around to pass the time. Of course, a lot of dingy stuff for adults can be found in SL a dime a dozen. However, if you want to seriously PLAY, which I can only advise against SL! The latencies are atrocious and the engine itself does not allow real 3D game feeling. The movements are extremely slow and overall running SL as a game just is not around. SL tried for years it also gamers to win and there are many projects which are working to Roleplaying, including Levelingsystem, skill system and so on ... but who is a "real" MMO or shooter is accustomed here is certainly not happy.
Two stars there by me purely from a gamers because the exploration factor in this game is only natural unbelievably large. There really is everything. So to just let purely zuschaun times and drift off for a few days in different worlds, meet people and SL must be regarded as highly complex chat, but it was definitely worth it.
