tjs282 - great stuff, as usual. Coupla dumbass questions if you don't mind:
1 what's OCN?
OCN = Optimum City Number. As I understand it (and probably wrongly!)
it's the breakpoint number of cities you can build/capture where corruption/waste will still be (relatively) easily manageable; once you pass the OCN, corruption/waste ramps sharply upwards in any cities further out from your capital than your 'OCN'th city.
OCN is set by map-size (smaller on smaller maps, larger on larger maps), and gets modified by the AI-cost-factor for the difficulty level. I can't remember exactly what the OCNs are for each map-size, but let's say that on a Standard map, OCN = 20 at
Regent (AI cost-factor=100%): then on a Standard map at
Emp (AI cost-factor=80%) you'll only get 20*0.8 = 16 uncorrupt towns, with the 17th being corrupt.
OCN is also halved until you've built your Forbidden Palace -- but you don't get (the prompt) to do that until you've founded/captured a number of cities ≥half the difficulty-modified OCN. So in the above example, you can build your FP once you own 10 cities at Regent, 8 at Emp. (I don't
think OCN changes according to %water, but I'm sure
someone knows for sure...
).
COMM civs get 25% extra uncorrupted cities, so on a Standard Regent map, the Romans would get 25 uncorrupt cities instead of 20, and at Emp they would get 20 instead of 16 -- that potentially means a
lot more uncorrupted trade to convert to gold or beakers.
2 what's this about choosing the Germans to prevent the AI having them? Are they notoriously tough on high levels?
You do know that at Monarch+ the AICivs get extra starting units, right? And not just extra Worker(s) -- and Settler(s) at DG+ -- but also mil-units: the best (resourceless) 'attacker' and 'defender' units that they can build with their starting techs. (IIRC, they get 2 'defenders' at Monarch, 3 'defenders' + 1 'attacker' at Emp, 6 'defenders' + 3 'attackers' at DG, and even more at Deity and Sid)
Since the starting-units are resourceless, for a lot of Civs, that mostly means that they have lots of Warriors running around. But SCI-Civs start with Bronze, so get free Spears/ Hoplites/ NuMercs as their defenders -- and MIL-civs start with WarCode (except Japan => Wheel), giving them Archers. This makes the Germans (SCI+MIL) tougher to attack early on, and also more likely to DoW you at an early(er!) stage at higher levels, because they are more likely to rate their military as strong vs. yours, at least until you've been able to build up more than just a few pitiful Warriors...
Or maybe my paranoia is showing -- I just started a Random-DG game (got the Byzzies -- on a Pangaea
), and I have the Germans right next door to me, but so far (Turn 80 or thereabouts), Otto has been reasonable...
