IMO, the biggest problem with the stone city is the distance. Defending the city from barbarians would require an independent platoon of axes that cannot contribute to defence of the other cities. Also hauling all the workers needed for hooking the stone and then back again sets a logistical challenge. However, I believe in 2metra's skills as a turn player and if he says he can pull it of by turn 88, I trust that he can. So I am also for trying the pyramids, but as majority of the team is not (even if we count Maga's vote), so be it.
