Is it just me, or are siege towers one of the most annoying things in the game? They take AGES to build, and you finally do get it built, it takes ages to crawl up to the castle, all the while your troops ignore your commands and stand in a line next to where the tower starts. And it's REALLY fun if you manage to get knocked out or run out of arrows or some other circumstance where the best idea is to retreat, because then you get to waste another two or three days to rebuild the tower while the castle gets to rebuild its garrison.
