Wes is correct - my aim in The Fringe is to crew mostly "normal" humanoids without any insane superpowers such as Nekovalkyrja strength or levitation. Of course, certain characters will outshine the others in certain tasks, but if I allow one or two characters to have a huge advantage over the others (such as letting one character be bulletproof, telekinetic, or be able to throw car-sized objects), it makes it very tough on me to make the RP enjoyable for everyone, particularly in combat situations. Modest bio-enhancements are fine, but I'd like to review any editions you make first, and rule whether or not they unbalance the crew too badly.
EDIT - Whoops, I just saw your reply after Wes. I'll look right now.
