Bug Options:
Turn on flexible difficulty for AI from Warlord to monarch
this will make it easier for AI that are low on score and a little more difficult for the top scorers. You however will eventually get stuck on the highest difficulty due to increasing difficulty which only applies to human players.
Don't be scared by the increasing difficulty option, it allows for an easier start and a challenge later on.
