I have horrible memory for simple names
Quite honestly, from all those I saw there, I can only think that Argos would be a good idea to take off. Mostly because I think there's too little space for a city like Argos (Sparta, Argos and Corinth are all in line and very close together). Instead, I'd give that region to Gaul, or any area that lacks regions.
Ih, and I'd strike off the navigable rivers idea... it seems to be a very common topic for many mods, but in the end it gets taken off due to the AI having trouble handling them (usually those rivers tend to get full with stack loads of pirates, than even get stuck when there are ports on the river)
Oh, and... your map looks quite bigger than the one of ExRM! It might be because the screenies Lethe has posted have a high resolution, something that my PC monitor lacks
(and on topic, it might be a good idea to post some screenies of the map here)
