3. Попытку эту я назвал неудачной потому как ни фига не получается. У меня по крайней мере не сходится. У Сида явно посложнее будет.

Score calculation

The scoring works by averaging your per-turn scores throughout the game. For each turn a (hidden) per-turn score is calculated as:

(Territory + HappyCitizens*2 + ContentCitizens + Specialists) * Difficulty

The total of all your per-turn scores is divided by the number of turns played so far to get your actual game score. I.e. your actual score is the average of your per-turn scores.

"Territory" is the number of tiles which are within your sphere of influence.
"Difficulty" is 1 for Chieftain, 2 for Warlord, 3 for Regent, 4 for Monarch, 5 for Emperor, 6 for Deity.

Early win Score Bonus

If you win before 2050AD, you get a bonus which is added to your regular score. The bonus is calculated as:

(2050 - FinishYear) * Difficulty

If you finish before 10AD, use the year as a negative number in the calculation.
Почему я и говорю, что это восстановление CM'a без бонуса.
В наших теминах (предполагается, что формула верна)

BaseScore = PlayerScore – (2050 - PlayerYear) * Difficulty
при этм Player Score = CM+(2050 - FinishYear) * Difficulty
получаем BaseScore = CM
