This has been bugging me for a while now. I recently went for an Honor start with Attila on a Great Plains Duel map (I am lazy and hate losing). Upon picking Warrior code and spawning a Great General, I did some math and realized that this one guy was sucking up over 14% of my entire civilization's GDP (not for long, though. Heheheh). I'm not sure if it's the case now, but i think at one point unit maintenance per unit went up exponentially (albeit with a very shallow ∂/∂x) as the number of units increased. Saving the Great Scientists from the PT and the LToP for a late-game bulb would easily cost several hundred gold, since each of those two dudes costs just as much as a work team or military unit and counts towards the total. Should Rosalind Franklin really cost as much per turn as an Infantry platoon? The opportunity cost of saving them rather than immediately planting them for the improvement is trade-off enough, in my opinion. Also, I don't think they should count against your Unit limit (not that that comes up frequently). And my number one complaint: Barbarians shouldn't instantly kill Great People (especially merchants. Grrrr...). Barbs should take them back to camp like any other civilian.
