In regards to 88/1 in a Cultural Victory:
The "1" means you only meed 1 foreign tourist to win a Cultural Victory. You have 88 which is many times more than needed to win.
Scythia has 0 domestic tourists. Your target to beat is 1 more than the highest domestic tourist number 0 + 1 = 1 (your target to beat). Scythia has an unusually high number of foreign tourists (88); your count of foriegn tourists is 88, the sum of all foreign tourists. Did you disable Cultural Victory or achieved it early and played beyond it? Normally, you would have won at 1/1, 2/1, 3/1; It seems odd that your foreign tourists jumped from 0 to 88 in a single turn; did it? Foreign tourists jumping from 0 to 1, 2 or 3 seems far more plausible.
