I wasn't a big fan of this game. Perhaps it would come down that I simply didn't give it a good enough go but I had played the game through and never found it – challenging except for maybe the first few rounds of my 1 play through. There was no battle tactics phase as you would have in certain other games, you simply attacked people if you were within the required hex range and that would be that. The researches, magic, etc have been seen better in other games.
Don't take this to say this game is awful, it was by no means bad. Visually it was quite pleasing and I enjoyed certain aspects of the humor and such, but it was just nothing amazing.
I wouldn't recommend it.
