Query: only if you are right into sci-fi

I didn't really like this one, I am a bit conservative with my campaign, and couldn't really take it seriously; Sci-fi is great, but not (for me) incorporated into a fantasy setting. I found it a bit over the top. If you want to incorporate a little Sci-fi into your campaign, i'd recommend I10 - Needle, which introduces a few aspects (lasers, interstellar travel) in the background, without tkaing over the entire adventure.
