Bug and Exploit that affect HotSeat Campaigns...
Bug:
The autoresolve is bugged in favour of attackers in siege battles..... it not consider the wall/castle defenses and attackers always have less casualities than if human control the armies in battle screen....
Exploit:
Hiring mercs, that is other unbalancing question, since first players can hire them and the others in same region don't this unbalance the game a lot in early stages..... Mercs should be available for all civs for equal and one hiring a merc should not affect the capacity of other to hire it! Because the order of playing is fixed, so a player has always the opportunity to hire mercs before the other!
Re: Bug and Exploit that affect HotSeat Campaigns...
The mercs exploit is a good point.
And yes Auto resolve seems to suck. They need to make it better. I think walls and towers do have an effect on the result though. What difficulty are you playing it on? I think the harder the difficulty the more often the AI wins even when the balance of power indicates it shouldnt.
