For those of you who enjoy Live games... this is a 5-player variant available on the English/Korean site... it will be coming to this site within a few weeks most likely so here is your chance to get some practice...
here are the rules:

its exactly the same set of rules as the Standard Dip you are used to, but with a cool map of the Mediteranian set in 1AD with five powers competing for dominance (18 dots to win also). Carthage, Rome, Greece, Persia, and Egypt each start with 3 dots, but there are a TON of neutrals so all the powers can expand quickly to 6 and 7 dots within two years.
it should be a LOT of fun to play this game as a Live-game go to that link above, create a new account just like you did here (you'll have 100

to spend) then join the game
