Great expansion. Wish other developers would put this much effort into them. This is the first expansion i have played in a while that actually adds to the original game rather than just tacking on a new, slightly inferior campaign.
Anyway, I'll just point out some things that you may want to be aware of.
Custom opponents (favourite new feature by the way; will add longevity to the game): for some reason, my custom player race starts out completely evil, and has all the descriptions associated with an evil civilization. This seems odd as you don't get the opportunity to customize the personality of player civilizations. Infact, the whole interface for this is rather confusing. Why not just have one screen with all the races on and the player then chooses which one he plays on. Ie; you get to determine the personality of all races, even the player one (it's just ingored when you play).
I have experienced CTDs (inconsistently) on loading, saving ship designs and on returning to the game after alt-tabbing out. I'm sorry I can't be more specific.
Also, does anyone know how to activate the cheats for DA? i tried the same thing as in GC2 with adding " CHEAT" onto the end of the shortcut target, but this doesn't seem to work (or if it does, perhaps the shortcuts have changed?).
Finally; it's nice to be able to build ships from scratch (with no base hull) but it's difficult to tell if your ship will be the appropriate size for a vessel of that type. I'm not sure how you'd go about dealing with this.
