Sorry, special rule: All the pop limits in the greece block are 1. I should note that on the map though for clarity, yes.
It looked like it might be the case, but that seems rather odd to create a special rule instead of just putting the ratings on the map for all to see. That's rather counter-intuitive.
I'm Jonno from CivProject.net. We are now hosting a full-resolution, 131MB, version of the map in our archive at http://www.civproject.net/Archive/CivProject/Mapboard Low resolution PNG files should be up shortly (in case your bandwidth or computer RAM is limited).
Regarding playing time: Over PBEM it'll take over a year, but IRL you can play it in 12-18 hours. I've played shorter games as well, in 6 hour 12 people played 10 round. If you'd like to know how we manage to play on this huge map, take a look at www.civproject.net, we have a full set of rules, as well as a forum. Hint: If you aren't 18 players, you only use part of the map.
It looks as if the hi-res version of the map was hosted on civproject which is now defunct. Would it be possible for you to host it on your own website so we can download it?
