So to what degree are we allowed to talk about it? There wasn't an NDA, and obviously we can't just give the documents away in their entirety...
I think my biggest question is if the antagonist's champions are persistent, or just pop up around the world through "magical portals" whenever the AI feels like it. It would be very cool to see a set of champions on your enemies' side grow over time, and thus I develop a sort of animosity towards them ("holy shit, that's the guy that killed my guy! and he's wearing his damn sword too..."). On the other hand, if they just get spawned in and then die in a few turns, that'd be totally disappointing.
And if I'm not mistaken, there seems to be some "tower defense" mechanics in there as well. I really have no idea how that will blend with a 4x TBS game.
