Random Dilemma

So here it is, for the 5 odd people that stumble my way, what should I do?

You see Im an amateur writer of sorts, nothing published, but it vents my imagination like sex vents lust. To put it on paper, to see it develop and to be able to describe scenes and details can burn hours of my live blissfully away. And now I have a dilemma.

Its not all that surprising, my attention span for most of the world is fairly limited, and so this was just a matter of time really. I have an entire universe, a 3 novel trilogy formed in my head with a set of characters, creatures, and back story that Ive been working on since I was in high school. Its all come such a long way, I had about 1/2 of my first book down when I took a break, formatted, and lost it. I know I know, idiot not making sure it was backed up. You cant call me anything I havent called myself. Anyways, for the november novel challenge I wanted to do something new, so I dipped my fingers into the sci fi world, and rather impressively, I thought I had it fairly sorted out. November turned out to be a rather busy month, so the progress was laughable, but I stuck with the story and carried it on for a bit. As of now though, my itch to return to my fantasy uni is growing into a rash. I miss vampires, dragons, wizards, magic. My choice in television and books hasnt helped that at all. But Im still fond of this sci fi bit. So a poll. Sci Fi or modern fantasy?
