Well crud, thats disappointing. I had thought it was an intentional thing, it made sense. If the warp bubble can help along however many ships, why not a terror star? Oh right, arbitrary implementation of a deus ex machina mechanic.
Again it would be nice if it was moddable, if I wanted I could create a free hull with 10000 hp, and a weapon that does 10000 damage for a build cost of zero available only to my custom race at start but I can't mod the speed of the terror stars. Oh Noes!!!!1!!! (Or so I understand)
Sorry, overly critical, a Deus ex machina mechanic bothers me anywhere I see it.
