Macedonians for me. But I hope the campaign isn't as easy as it was in he frist, after you take over greece.
Well we can hope they have improved the campaign AI alot, their "difficulty" has always been represented by just giving the AI more bonuses, which whilst made the campaign harder, it was not in a good challenging way. Hopefully the difficulty is based more around the AI rather than balance destroying bonuses.
The AI spammed armies endlessly due to the massive bonuses in gold etc and also made the battles less immersive if you changed battle difficulty as the AI units were buffed up, meaning you'd see one of your awesome units struggling against some my old friendgy unit. Also the constant spam of armies made for repetitive boring battles defending the same shithouse over and over again whilst you attacked inbetween.
Well, the way armies are done looks a lot better this time and they wont be so easily replaceable/spammable so that's one thing that should be better. But until I get to play the game myself I don't have high hopes for any "amazing AI", I won't really be dissapointed if it isn't awesome, I'll still play the hell out of the Campaign and have a lot of fun in multiplayer.
