For ICW, we stuck to the more prominent canon names, as well as some community suggestions from the "Name That Ship" thread. However, the way ship names worked in EaW was pretty stupid; it'd read them from the list essentially straight down, so you'd really only ever see the first 5 or 6 names. If people are particularly attached to having certain names in Ascendancy however, we're open to that, or just to community-generated ones which sound like they fit the faction.
For planets, in the randomly generated scenarios the names are randomly generated within a specific planet type, though when we make the scenarios we'll make sure the right planets are in the right spots with the right names. As for types, we're not quite sure what we'll need. A lot of the vanilla ones will, but some (Ferrous comes to mind) won't.
