"Colossal" may be the refrence to "Very big ships with special functionality". I don't think that it'll be PL. I think "space first", EVE has this lesson with "Encarna" exspansion.
Incarna?
I thought that was walking around anyway.
Planets are in space, the ability to fly down to them (and land on outposts and do some other things) has been in the series since 1994. So it's just a level of detail that was deliberately excluded from the initial release, but I don't see why ED doesn't deserve to go to that level of detail (granted it's much more complex 20 years later) it's part of the background of the Elite playground.
