Now that I look at the rules again, I see our next unresolved issue. I don't see an agreement on the actual numerical benefit of the farm Bonus. (We discussed them giving you a cost reduction on upkeep)
Well, I figured a good place to start is calculating the value of the other 2 types of bonuses from resource points. I just did the math, starting with a Mill. Ignoring upkeep, and asssuming a city spends all Flavor Points on Mills, and builds Mills as well, it can reach level 5 on it's 19th turn. After this point, the bonus aspect of the Mill is no longer used, and over this "lifetime" each Mill has individually provided a savings of 1500 for that city.
As luck would have it, the math also shows that Motherlode chance at a Mine averages to...you guessed it, 1500 in a 19-turn period.
So to make Farms fair, their bonus to upkeep should be comparable in value. 1500/19 comes out to an icky number, so we can round up to 80 or down to 75. This is how much a Farm should save you on upkeep each turn. Thoughts Kaed?
(EDIT: I'm a fan of rounding down now that I think about it. The Mill bonus is worth a fixed amount over the course of a game, and the Mine is a random chance. Farm however would reliably crank out the same bonus value every turn forever)

There's gotta be a good joke in here somewhere.
