In my original Spec:
http://spreadsheets.google.com/ccc?key=0ArGEV8QiVgM6dFFNMndKMEtnbGZWNWZGalZfT2VtckE&hl=en#gid=0
Towns never got a free food bonus, in fact the only food bonus they ever got, EVER was from Organic Cities.
In my Spec Towns didn't start w/ 2 Hammers either and also only got 1 hammer bonus from Personal Robots.
Maxed Town Total (on a grassland) under my Original Spec is:
3

2

6
In retrospect the commerce yeild should be less than in my original Specs, and probably max out at 3. (+1 at cottage, +1 at village, + 1 for route)
However, assuming we keep the other improvements unchanged, the make for
Townx3 = 9F, 6H, 9C. There clear winner becomes the Farm + Industry + Trade Center
So Why ever bother building Town? For the Free Specialist.
In Terms of balance and AI choices:
First you can't build towns except on Flatland adjacent to freshwater. (note that with Jungles still flagged as freshwater, which is something I still disagree with, and it would make your freshwater calcing code alot easier Aff) this could still become a lot.
This is also why Cottage->Towns in my original spec could not be built on marshes (who wants to live in a swamp?) as an extra limit on their number.
When Automation is choose what to build when the choices are Trading Post, Workshop or Town:
No Freshwater or on a Marsh? Trading Post or Workshop, depending on the need for commerce vs hammer.
Is fresh water available? Most cases you'll want a town. If the underlying terrain is Desert or Snow though, you might want to go with the workshop or trading post instead though since the food penalty does not have any effect on those terrains.
I didn't know the Town Hall, City Council would have a free specialist all on its own, I'm not sure if it should. The free specialist per town is good enough on its own.
