In one of the video interviews out currently a developer says that he won't talk about missions later on in their demo because he did not want to reveal the story. Does that mean this game is very linear? I had the impression that it was more of a open world type strategy game where you always had options of what to prioritize and where to send your troops. If something say always happens, like a scripted event, after you do UFO mission D, doesn't it lose some of its replayability value?
I was hoping there wasn't a huge deal of story based missions, just randomized action until you eventually get to the root of the invasion.
