P.S. The KaM Remake is a TSK Remake, not a TPR Remake. Only TPR features that fit with the game style, are balanced and we approve of will be implemented. (e.g. the fisherman's hut and TPR soldiers)
I'll try and think of more Town Hall ideas - seems like a good opportunity to come up with a cool new feature!
Were there plans to make a building that your serfs could hide in if your town is under attack? Because the Town Hall could always serve that purpose.
Age of Mythology (possibly other "Age of..." games as well) has a "Town Centre" building with an ability to ring the "Town Bell", causing everyone to run inside of it. This almost seems too perfect, since the Town Hall's icon is a bell xD
