The answer I quoted said 8 promotions (before the edit), I meant that I knew ways for getting 9. But those were also answered already.You only needed to say one of the answers, note I said needed, so that means someone here is right. Here's a hint, alhimik is wrong (otherwise, you're going to have to tell me the 2 other situations that provide more promotions, btw, why can't you answer? edit: nvm, looked at the rules).
Spoiler :Onionsoilder is right. Btw, random events weren't accounted for.
The other two solutions were stated by UWHabs and ruff_hi, except since Onionsoilder answered first he gets it. I'm surprised that you guys were able to answer that quickly! You know you're not supposed to look up the answers, right? This is all coming from your head!
So you're up Onionsoldier!
Okay, will do:
What is the highest amount of Commerce any single tile can yield?
I think I'm allow to correct. A town with Free Speech in forced, gains 2 extra commerce. Also with Printing Press, you get another commerce. Can't believe you guys missed that!
Well, actually the question (if I understand correctly that is) it says what is the highest yield you can get of commerce on one tile, it didn't say anything about having fewer requirements or not.
Anyways, the answer would be:..?, Camel Archer, Cuirassier... that's all I can remember actually, but there's tons more I know. Btw, does it include UU?
