Great game, I will spend few hundreds hour with. This game will become legend as Master of Magic before.
The game has very nice graphics. It is quite simplistic and I can imagine some people would not like it, but I love it. The rather simplistic approach helps you to orient on the map. I hate, when you loose the battle, because you were not able to see an army hidden behind some "cool graphic eye-candy".
When the game was released, it had stability issues. It was very unfortunate. This game deserves to be "turn based strategy of the year". Now, journalist write how terrible the game is. Sad thing. When I bought Mass Effect one, it was barely stable at the release date and it was fixed after a year. Mass Effect 2 was playable after two months (many people were not able to go further than intro). Stardock stabilized the game after two weeks after the initial release.
Summary: Great game with lot of cool features. If you want to play some simple game, this game is not for you, but if you are nerd or you loved the good old Master of Magic, you must have it.
