Just tried this.
Build pyramids as fast as possible with non industrious leader and without stone. About 106 turns on epic.
Then in separate game gave myself 106 turns to see how I could develop my civ. I managed to get 2 poorly developed cities out plus capital. I also had 8 archers with 1 promotion.
Assume my scout has found the opponent and it takes me 30-40 moves to get my archers to my opponent.
Does this sound compensation enough?
Archers?! I'm sorry but this is a really useless attempt to deal with the pyramids. You are much better off warrior rushing. Just build worker, maybe a barracks, then warriors. You should easily be able to get 3 or 4 warriors to his capital before 106 turns. You have 3 cities, are planning to rush, but don't have bronze or horses. When rushing only settle to claim these resources. In this case horses is much better, doesn't matter if they are miles away. Settlers and workers waste time and hammers that could be spent on units. That means 2 cities max. What are you going to use the extra cities for when your opponent is dead?
In my test on these settings I played vs myself, augustus (industrious) vs hatty. Augustus built the pyramids, three cities, three workers (trying desperately to hook up iron), and had a total defense force of three warriors when my hordes of chariots arrived. It is true that hatty is pretty ideal for a chariot rush, and I knew roughly where the rush target was (although I did try to explore realistically). Also, if Augustus had had metal in his capital he could have put up more of a fight, but even then only if he knew the rush was coming, and he still would have lost due to choking at the very least. I actually could have got a chariot or two there much faster but I wasn't sure if that would be enough (it certainly would be).
