I find the town hall as a building a bit lacking. I mean it is supposed to be the centre of the town, right?
How about making stats viewable there like:
- What builders are currently on the job
- How much is the total resource production
- Show the max troop potential
Throw some more ideas out there and then maybe that townhall would feel more worthy of protection.
Why not add a little more the those builders huts too like, what has this particular builder accomplished? It would be cool if that hammer-wielding tough guy would join the battle on defenses too!
