I understand that in reality, the pirate station, would ideally be somewhere less than 1 G, so space sickness is lessened between life between station life and extra-vehicular activity.

However, for fantasy/sci-fi gaming 1 G is pretty common on stations and aboard ship (at least what you're used to on TV - Battlestar Galactica, Trek, Serenity, etc.)

So I guess I'm designing a facility using normal earth gravity. Whether this is created through centrifugal spin of the asteroid, or by artificial "grav unit", I'm not sure - I think the latter.

Is this realistic? Probably not, scientifically, but for gaming I think its the direction I'll go and gamers would expect...

I'm not trying to create the type of beds found on the space shuttle or MIR station. That's low tech for my perceived sci-fi setting.
