Pharaoh.
First mission in the campaign you are tasked with building a medium pyramid.
Who hasn't played the game: building monuments takes quite a long time.
So, get my city running with two 16x8 blocks. Trading, food production, stone
quarry all set up to the point where I really don't have to interfere anymore.
Start building the pyramid, make all the preparations needed and see them starting
to lay out the first layer, before I crank up the game speed, close the monitor
and go watch some telly.
Come back 45 minutes later, hoping to see the "Mission Completed" screen, but no.
I check the pyramid and only 1 layer's done. I check the stone quarry, work camps,
stonemason and wood carpent- FUUUUUUUUUUUUUUUUUUUUUU-!!!!
Forgot to import wood for the scaffoldings.
