Fredrick starts of with -2 with Stalin so it is not to unlikely that we would no longer be worst enemies if we make peace.
I'm not sure what you're arguing for. Is it "Let's not trade away Alphabet to any AI and take whatever steps are necessary to achieve that goal?"
If that's the case, I respect that you have that opinion.
Personally, I believe that Joao having Alphabet will be a good thing. If we can get so lucky as to have an AI research Currency for us, then after Masonry (if needed--Pericles might be an AI who would trade it to us) and Horseback Riding, we could go straight for Code of Laws and get Currency from that AI. Such a situation would be great.
I do suggest that we plan to trade Alphabet to Churchill for war on Frederick, also to give Churchill a chance to research Currency.
Besides the chance for Joao to go after Currency, I would love to see Joao bribe an AI into attacking us when we declare war on Joao, to save us from getting negative Diplo Attitude hits from declaring war on an AI that is likely to meet more AIs.
I.e. Maybe Joao has met 3 AIs but the AI that he bribes has met 10 AIs, so we don't anger too many AIs by declaring war on Joao and then we don't anger anyone for the second war, not even the AI with whom we go to war. And, such a war bribe leaves the AI who got bribed not in a position to invade us, since no war was being plotted at the time.
Add to that that I think that the right AIs to enable are those that we can easily clobber before they can reach Feudalism (as well as AIs whom we can get up to Friendly status or who will trade techs easily--such as Pericles, Peter, Willem--and thus can remain our long-term tech-trading partners).
Based on the Cultural Borders from the test game, we'll have to "pick" between defeating Frederick, defeating the Light Blue AI, or Vassalling one of them. I wouldn't be surprised to see such "choices" littered throughout our path. Of course, we could just defeat everyone, but doing so may not be ideal.
Whether we kill Frederick or not, I'd rather not enable him, as, if we leave him alive, he may come seeking revenge later.
I also really want Churchill as a Friendly AI as he's relatively isolated, so he won't have a lot of AIs with whom to trade techs that we sell to him. Then, we can both enjoy overseas, foreign Trade Routes until we've outgrown him and can take over his Cities ourselves.
If we have Pericles as a neighbour, I'd love to make him a long-term tech-trading partner, meaning reducing WFYABTA now and never needing to get him to Friendly (why bother when he readily trades techs that only a few AIs know?). If we have Pacal or Alexander as a neighbour, then that AI isn't going to be an effective medium-term tech-trading partner if we meet that AI before trading 3 more techs, as they both will stop trading after we've received 8 techs in trade after having met them, and 8 techs will come up pretty quickly once we factor in techs such as Mysticism, Meditation, Priesthood, Mathematics, and Aesthetics.
To me, this game is a teching game, so matters of teching are important.
We're going to capture Cities because we believe that doing so will increase our overall tech rate in the medium term, even if there's a dip in our tech rate in the short term due to whipping away population points.
I think that we should approach multiple aspects of this game from a tech-emphasis approach and I do believe that incurring more WFYABTA than we need to, while it is only really a small concern in the grand scheme of things, may lead to us having to self tech an extra couple of techs, which does slow down our victory date.
Managing the AIs well is a big part of winning this particular challenge, particularly with the restriction of only being allowed to have 1 Vassal.
But I'm fine with the PPP.
Well, I have run out of time to play today, so it will have to be tomorrow, unless someone else wants to volunteer in the thread and then play through the PPP before tomorrow.
I enjoy planning more than the playing, so keep that fact in mind if you have time to play turnsets when I throw out a plan.
