I personally <3 fantasy and magic, or any sort of fantastical powers like that, and therefore... if a storyline even has a small bit of magic in it, I'll like it. Usually. So if you decided to, say, have a futuristic setting in which magic existed (even if not widely known) I'd still have loads of fun O:
As for realistic futuristic... I'm already on a board that's trying to do that, albeit not very well :B we currently have about 5 or 6 members, we need more to start the plot, according to the admin.
