Ok,donnanocerino this is for you.I`ve found this review so i hope it helps a bit.
Of all the virtual worlds we visited, Second Life is the one we want to come back to the most. The people are friendly, and the environment is stunning—and we were able to help build it.
When you first join, you are taken to Prelude Island to acquire basic skills. The tutorial process is relatively lengthy; it took us 20 minutes to get to the mainland, but we needed that time to get comfortable with the relatively complex controls.
In Second Life, your avatar is completely customizable, with myriad variations of skin tone, eye color, hair type, clothing, shoes, and so on. And you can make changes to the world itself: You can purchase some land and build a house. Building in Second Life relies on a series of menu-based scripts that take some time to master. Although commands will be familiar to anyone who has used a basic design or graphics program, they aren't quite point-and-click.
After finishing your time at Prelude Island, you are transported to a standard starting area. Here you can check which of your buddies are online and move through the world by walking, teleporting, or flying. The last is definitely the most fun.
Although you can create weapons and do battle in special areas of Second Life, that is not a major draw. The game is designed for a more sophisticated virtual citizen, one who would be more interested in building a 3-D replica of the Eiffel Tower than in blowing away other denizens.
