Hmmm.
Hmmmmmmmm.

I would like to forward my interest, specifically in filling a hole that doesn't look like it has been considered, and put forth an application for a medic. But I do have a few questions that you may have answered and I missed, so forgive me if any these are redundant:

How advanced is technology? I know you listed several series that I am unfamiliar with, but just a galactic average on computer science, data storage, food processing, flight technology, etc, would be neat. I understand GURPS Tech Levels, if that helps.

You did say that aliens were okay, but also said you wanted a mostly human team. Xenobiology would kind of be necessary either way, I suppose, but how many species are well known enough for a human to learn medical practises for them? 

More on tech: How are you getting around the travel times between stars? FTL, cold storage, something else fun and exciting?

If I do end up making an alien, precisely how truly [i]alien[/i] can I get? Size would be a problem on a human built ship, as would certain biological issues, so that question becomes somewhat important.

And lastly, how do you feel about AIs?
