What imaginary world you prefer to live in, out of A and B (feel free to add whatever scenarios you want to what I have outlined), and why? (no going around the question!)
A. A mysterious, medieval place sometime in the past, where people have magical powers. But there subsists an oppressive power faction and feudal social system. There is often war, and lots of injustice. However, you have somewhat more profound powers than other people (but having special powers in particular is somewhat taboo). And there is lots of wonder to be explored (it is a mysterious and magical world with lots to be discovered; like talking animals etc). There are many of magical battles to fight and mysteries to be solved...
B. A future thousands of years from now, where technological capacity has expanded to the point where many things are possible (time travel, space travel within reason, medical technology and practice is superior, super computers, new synthetic materials e.g. super shields, invisibility cloaks [:P], AI, everything else you imagine). Communities are largely politically stable, but many threats still arise (biological warfare, concerns about human rights and privacy etc). People sometimes go missing, and there are so many people on the planet, nobody seems to notice. many things that go on, are easily covered up. Technology has enabled many things, both good and bad (i'll leave the gaps to be filled by you).
Also, what other fictional world would you be most interested in exploring, that you have come across? or have you created or imagined a world that you would like to share?
