Anyone use a Fortified City?

I usually use 3 types of forts:
- Castle - for smaller maps or for nations that don't have too many troops or mages I'd like to buy later. Also for nations that have good resource-intensive troops for early game
- Mausoleum - in other cases when the nation needs walls (lots of casters and few big troops to block the gate)
- Watch Tower - for the nations who will rely on masses of undead (for those, the walls is rather a drawback)

All 3 cases seem to work...
