SecondLife is a low-key yet vast online virtual world created in 2003. everything / 99% of its content is made by users, and is less of a game & more of a digital universe. it's pure interaction & sandbox. i've had an account for a year but only started playing and becoming passionate recently. learn more here on the official site , or the wiki. ignore the weird realistic humans on the website there's so much more than that, however often real-world currency is involved (though you can learn how to maximize freebies), and you need to use an alternate viewer to play (such as firestorm. ) as the default viewer will make your computer melt into pure, gelatinous slop.
