Hmm, that siege was quite the clusterfark.
I had no idea where to attack, I shot the gate to 100% damage but still couldn't enter through it. Didn't seem to matter since climbing walls seems pretty straight forward while carrying a long spear, and takes about 10 seconds. Wouldn't want generation deficient attention span to quit playing, right?
Guess you can use the bow hero to shoot a bit, they have longer range and can attack where there's no tower? I did get a few opportunities to shoot at yari units inside the walls without getting shot at with samurai archers, regardless.
Eventually I sent my katana samurai up the walls at the gates, they didn't open, the katanas lost against yaris, I think half of them were ashigerus even. The AI had sent his cavalry and at least one unit of yaris out to die before that, before I even reached the walls. Then I sent my yaris up and suddenly the enemy started running out the gates, shattered. I have no idea what happened at that point. Suddenly I won the battle without being anywhere near the keep-thingie.
Some of these games takes a while getting used to, but I can't say I'm impressed after this.
I like how there seems to be a lot of choke points on the map though.
