Creative Assembly does it again
The Good: Amazing graphical detail just watching your army standing in the field with the sun gleaming off their armor before the charge or watching catapults firing flaming rocks in the dead of night adds to the huge battles in the game. The Ai is greatly improved in Rome the units fought like paper rock and scissors with spear beating horse, infantry beating spear, etc.... I charge my calvary right into a blob of infantry first time I played and soon I was without calvalry. Now a lot of infantry units are strong enough to defeat calvalry just by standing still. Also seige units have different accuracies so a trebuchet may miss 50% of the time but late age cannons are deadly accurate. The campaings are so detailed most of the fun is generated by all the things you can do other than battles between armies and if your more of a casual general you can select a short campaign.
The bad: well since it would be boring waiting 30 minutes in the grand campaign for another player to fight any battles during his/her turn you can only fight custom battles via multiplayer and not the campaign. I wish campaign mode had been an option but I can see why it just wouldn't work. Well that's it I really haven't found anything I dislike about this game.
