Secondlife is a different take in a mmo rpg , its not a game persay but more of a virtual universe, where you create an avatar based roughly on what you like, then you can either save up the lindens ( money for secondlife ) or use buy some for yourself and make up your avatar ( person ) to what you like.

There is many diverse cultures in secondlife you can "be" a vampire or furry or just be yourself and go to clubs and meet other's interested in the same thing. There is extensive RPing possibilties in SL. From Gorean Sims to Vampire Clans to Fighting clubs and Samurai Sims . It all depends on what you want to do.

From my experience with SL it can be a very enteraining way to spend some time with people. Explore the user based world or as stated you can shop in the numerous stores to outfit your avatar to your tastes.

Also stated there can be drama when people use SL for dating and cyber sex. Thus there is also a pg rated SL for those under 18 yrs of age. Pretty much every real life scenario can be done in SL.

From biking to skiing, to hang gliding to motorcycles,robotics,anime, anything that you can imagine most likely is there. From dance clubs to rock clubs , to user created live events where ppl actually perform live via SL. Many have taken it very seriously because of the nature of making real world money out of user created content in secondlife. Thus many ppl buy and sell land and make alot of money , as well as clothing and buildings etc..

Those can build up the lindens and made into real world currency and many have made alot of money.  but like anything it doesnt happen overnight and takes alot of time and effort.

Casual users can enjoy it as well and its quite popular.  As stated also there is guns and combat sims for those interested in those things. Like anything if you look something in particular you will find it. If all you seek is sex then thats all you will find there. There is alot more to that virtual world than most think.

Its not a normal game and for many there its just an extension of the real world but in virtual form. And it is not for everyone. :)
