I wish this game was more difficult.
The first time I played through, I did the usual civ thing and set the largest world possible against the most enemies. It was incredibly boring, as I ended up researching every single spell in the entire game before anyone even bothered to declare war on each other since the map was so huge. I think I had nearly 40 cities before I even finished exploring my one continent, to say nothing of all the others I didn't even see.
So I decided to try something else and went with a medium world with just 4 enemies, but taking into consideration of the normal difficulty chosen previously, I just went straight up highest difficulty level. It wasn't even remotely a challenge. =| It's not so much bragging as it is taking advantage of an almost nonexistant AI. For one, for some reason the AI adore declaring war on every single one of their neighbours except you. I don't know if that's a bug or not. Another is the AI's incapability when it comes to expanding. It sure likes to take its time getting new cities considering there's literally no downside whatsoever to spamming cities everywhere. Thirdly, the AI loves to just straight up donate money to you for paltry returns. Once you get an alliance with people, almost every single turn they'll spam you with really dumb trade requests. Things like giving you 100 gold for 14 mana... The battle AI was pretty good though, and it synergized very well with its use of magic. Just the strategic part was completely inept.
Mrm.... the game is entertaining... but some mechanics definitely need to be changed and the AI could use a lot more work.
