I got Rome Total War II and I am loving it. The Empire Divided and Augustus scenarios are great. The base campaign has been a little weak, however.
One item that I would like to see improved for the base campaign is Greece. Where is the Achaean and Aetolian leagues? There isn't enough cities in Greece to do it justice. I feel like Thermon and the Aetolian League plus Patras and the Achaean league should have been present. Also perhaps Corinth and/or Thebes.
Is there a mod out there that adds some of these cities without changing the rest of the map? I honestly think the other areas of the map are great, including the East. Some of the new Rome Total War I scenarios for Greece were brutal because they added too much cities and messed with the units too much for my taste.
A few other minor items that bugged me a little with the main campaign as well:
1. Most civs not having the ability to make archer units which limits the strategy
2. Seleucids not owning Seleucia (lower Iraq) directly.
3. Rome owning Magna Greece but not the Estrucans (I think the opposite happened in history)
However Greece is my main concern as Athens and Sparta (and to some degree Macedon and Epirus) are kind of unplayable without these other city states to conquer and fight with.
