On a more realistic note, I have actually created a semi-board game I like to call "European Crisis".
I used some flags (national flags for ARMIES, naval jacks for NAVIES, and air force icons for AIR FORCE) and placed them on a map of Europe (from the mid-Atlantic to mid-Russia) that was published by National Geographic in 1975, so there's East/West Germany and the USSR.
Either way, it involved something like 60 or so countries (not all European; I also added in African and Middle Eastern countries. Only the tip of Africa can be seen from the far-out European map, so I have to flip to a different page to get a map of Africa and continue from there.
Anyways, there were 60 countries but I could only get 6 players max so I we left some countries out (mostly African) and each player got 7 countries with special rules:
a) they were not allowed to ally
b) they were not allowed to support each other unless in real life they are allies
It was very complex and fun. There was diplomacy, pacts, battles, wars, campaigns, a United Nations-like organization called "NOW", which stood for "Nations Of (the) World".
The rules were basic: it was turn-based and each player was allowed one order per flag (unit). The unit could either battle another unit that was less than or 1" away or it could move 1". Like Diplomacy, support moving/holding was essential. Another army about 1" away can support the other army, dislodging the enemy army. If an enemy army is dislodged 7 times, then it is "destroyed", which it is removed.
It is fun yet complex. Sorry for poor explaining, this game is nearly impossible to explain.
