Second Life
You can try exploring Second Life if you wish although it takes some time to get going. You have to learn how to navigate and fly. Second Life has changed over the years and is a weirder place than it once was. Educational institutions such as the University of Auckland have a presence in Second Life, but it seems harder to visit these places.
