I also got seduced by the Stardock rebate offer
Seriously, I hadn't heard of the game before I received that promo email, tried the demo and discovered that it was my kind of game. Turn based, lots of varity, strategy and tactics, elements of roleplaying. I'm a veteran of games like Stars!, Space Empires, Heroes of Might and Magic. So I ordered the full game.
Meanwhile I'll play the demo. This is one of the few games that have a demo that can keep you occupied for a while (Railroad Tycoon 2+3 also comes to mind).
