The AI launched a sneak attack on me last night.

Perhaps "advanced farming techniques" and "genetic engineering" as tech tree items, or just a background increase in one's ability to feed one's people at major technological milestones that aren't really tech tree items, but come in to play silently?

I'd like to see the ability to upgrade resources as well. At the risk of getting too "civ-like" I think it's an appropriate piece for the tech tree.
