Since some of you don't know the rules of the original Ankara Crescent, let me explain the rules.
The game Ankara Crescent is, in some aspects, (but hardly any) similar to the board game diplomacy, in fact Allan Calhamer admitted back in 1975 that he designed the board game as a more simplified version of Ankara Crescent. He wanted less rules and less strategy.
The object of the game is simple: You need to end the year in Ankara. You play by moving units across Europe with the aim of eventually getting to Ankara. How units move and where they can move is dependent on where they are, where they use to be, where they want to go and how far away enemy units are. More experienced players will predict the movements of their opponents multiple turns in advance and move accordingly to prevent them from getting there. A few years back, I think it was gobbledydook, was able to predict one of my moves 30 turns in advance.
If you want to know all the rules, I recommend buying the rule book. You can probably find it floating around on eBay, thats how I managed the track it down.
Please note that while the rule book is useful as a starting guiding, it hasn't been in production for 26 years and as such ignores some of the official rule changes such as the Southeast Approach or the Detroit Convention.
