I forgot to add Willow is also in the virtual worlds of Kitely and Inworldz. I’m not in those worlds as much as Second Life.
While Kitely is technically interesting and may be the future of virtual worlds it is a little too “geeky” for me. I spent a couple of decades working professionally with computer systems and I don’t want to spend my time trying to figure out how something technically works. I’m also not fond of the its every sim is its own world data setup that is only loaded when someone accesses it.
The Inworldz world is almost the same as Second Life but without the exorbitant land prices.

In my opinion Kitely and Inworldz are hindered by not having enough population. Since I’m in virtual for social reasons so that is a problem.
Since Sansar may eventually supplant Second Life; I know LL says it won’t but with the haphazard way they do thing who really knows. So, it may be a good idea to keep your options open if it doesn’t cost too much.
