This has been posted in two other threads, by Annatar and idunno16 respectively (or was it idunno116, my apologies if I've gotten it wrong), and Annatar noticed Mittens paste the link in IRC, so it's apparently not preempting an announcement.
Considering the other two threads started out as anticipation and speculation, it may be better to move the discussion here, but then again it may not.
As far as my own personal feelings go, based on the screenshots alone I'm not overly impressed, but I've always been more about the mechanics of a game than the visuals. When one accounts for the fact that Brad has mentioned it will be somewhat like Populous (though obviously with other things factored in and influencing it, and done in a way that only Stardock can do it), and more to the point that it will have multiplayer and, for lack of a better way to put it, a mod universe, I become much more interested in it. I do hope the graphics and interface have improved somewhat from what gamespy has by the time it launches, but since this is Stardock we're talking about this is a hope that may actually be realized and less of a legitimate concern.
However, I am not yet ready to justify preordering it, even if it were possible. Sorry, Brad. I know I'm picky.
