As stated by many, SL is not "a game" it is a social platform and because it is all content created by the users, it is unbelievably verstile. That being said, I don't feel it was ever designed for ease of use. I have seen some people on here for 5 years that still can't adjust their clothing to look remotely decent.
If you are somewhat computer savvy and feel you are capable of learning, this is the place for you! Stick with it and wander about for a while. Keep in the forums too, one good friend can make all the difference! If you are not computer savvy and the littlest thing confuses you when it comes to technical aspects, I would probably save the time and buy an actual game, such as Sims. SL is the most amazing place tho. The possibilities are endless!
