Definitely modern settings are my favorite - and that is definitely also bias for sort of... Imagining myself as a more likely participant or viewer. I also enjoy medival fantasy settings, but for Scifi, while it is my favorite fictional general genre, it works kind of a bit less for me. So kind of... Moden, than Fantasy, then Scifi.

... That said, I also quite enjoy fanfictions and fanfiction settings. Pokemon, Digimon, even like... World of Warcraft - all excellent settings for growy stories! :D
