WoundedKnight,
No farms? Could you elaborate on this? Aren't they important?
Generally no, not except for resources that require farms. Here's why...it relates to the final benefit you get with upgraded improvements (i.e. improvements with necessary tech, location, and civics if applicable):
I build watermills everywhere I can, mines on mountains, and cottages everywhere else:
Town commerce +7, production +1
watermill production +2, food +1, commerce +2
I almost never build these:
Farm: food +2
windmill food +1, production +1, commerce +2
lumbermills production +1, commerce +1 (if near river only)
The initial farm food is just +1, and the next +1 you don't get until biology -well after almost all of my cottages have become towns. Lumbermill benefits are minimal..you get the same production and a lot more commerce from cottages. Chop the trees down to rush settlers or wonders, and build a cottage, watermill, or mine instead to restore some productivity (and give more food, in the case of the first two) and generate far richer commerce.
Windmills don't strike me as being particularly worthwhile (they are down one production in comparison to watermills), although the AI builds them all over the place. I use watermills instead of farms -- as much food bonus as early farms (+1), plus the production bonus of a forest (+2 hammers) and extra commerce (+2, +3 if financial).
Cottages take time to develop, so I focus on building them early and stick with them. I find that production is more limited than food in most games, hence this algorithm. The increased commerce will put you ahead in tech, and the increased productivity will pay for itself in short order by giving you faster buildings and wonders in the city. Of course one could make a case that there are appropriate times to build farms. Especially if you are desparate for a few extra citizen points to get a couple more specialists for GPs at the end-game and are willing to sacrifice a big chunk of productivity and commerce to do so. But in general, I would rather build more cities and have them focus on production and commerce, instead of having cities with huge populations but poor productivity and low income.
Whatever kind of victory you are aiming for -- conquest, domination, culture, spaceship, etc... -- you need production and commerce to get there. And improvements that produce a combined total of food, production, and commerce of +8 (towns) or +5 (watermills) obviously offer much more to your city on the whole than improvements that add only +1 or +2 (farms and lumbermills).
