Second I will ask you to check out one of the earliest Civ4 mods on the forum, the
TAM.
Too bad, there isn't a BTS-version for us mac players, yet. I'm sure, TAM has got some considerable tweaks over the years since I've played the Vanilla and Warlords version (and loved it). But
PAE has certainly some strong features (ranged combat, i.e. no suicide cats, cultural boarder change resulting from combat outcome, daring new revolting and mutiny features, a very unique "atmosphere", and much more).
Meanwhile, I also adapted your smaller Mediterranean for a private modmod of PAE with all the civs I
had to add to populize your immensly huge and therefore quite peaceful and empty Central Mediterranean settled in many cases very close to each other: Epirus, Illyrians, Thrace, Sparta, Thebes, Lucans, Bruttians, Samnites, Etruscans, etc.. Loads of fun!
So, if there wasn't this cap of an 18 civs maximum for macs (because mac compatibility requires an unaltered dll), I would either from you or Jabarto request an ultimate Giant Mediterranean map. Well, maybe this will be happening after Civ V
