Dominions II is a rather "HC" fnatsy strategy game. You are one of the pretendeing gods, and your goal is to become a real god by destroying your enemies and spreading your Dominion, the embodiment of your divine power. Dominions I has huge batles, incredible amounts of depht, and i believe so will Dominions II have.
You can always try the demo of Domiions I. If you liek the demo, you'll like Dominions, and then you'll propably like Dominions II also.
