I left the second spoiler thread in 790 AD when Greece was eliminated.
790 AD
Since we still felt our empire was a little small, and Egypt needed to be taught a lesson for their earlier brutality, we spent the next 8 turns to move the bulk of our forces over to their part of the world and proceeded to take 10 of their cities as well.
In the year 970 AD, we were told to stop our efforts by the gods above. Something called the 'domination limit' was in risk of being overstepped, and they would not have that. Later, we had in fact to abandon a tundra city and give back one former Egyptian town to avoid that very same atrocity ...
Our purpose in life became to honor the Celtic gods to the best of our ability by rushing Temples and Cathedrals everywhere, as well as other buildings.
Finally, it was enough. When we passed a 100,000 culture, we were allowed to dominate the world on the very same turn ....
of course by then the domination paled in comparison to our cultural tribute, which we claim to be our true victory.
But the history books will record that the great Celts have done both feats.
