Tried out the demo, and it's a fun little game,but from what I can tell, it's entirely tactical, not strategic, and there appears to be no way to save the games. What I really liked about Advanced Tactics (beside the scenario editor) is that it reminded me of an old game from the '90s called "Empire: Wargame of the Century"
(I tried to post a link with an image, but the forum wouldn't let me--but you could google it...)
Advanced Tactics reminded me of this, because the cities had production, making much more of a grand-strategic type of game.
Vic, if you happen to read this, please consider making it!
