Turn 256
Lots of good comments, so I won't address them all. I did really appreciate the reminder that I can partial-research techs to keep people in the dark. I don't have to really commit to a path for about 2 more turns, but my gut really wants to make a play for the Kremlin. One of the main factors here is that Mackoti is our only competition, and if he lands the Kremlin with his land edge, it might be game over even if I think REM is in the better position right now. Here's how long it would take me on a direct route:
That's 10T on full tech, and I can easily wrangle together the gold needed. That number might drop to 9T with the completion of Oxford (not sure). Kremlin is probably a 4-5T build. It's crazy how much cheaper that wonder is than SoL. (Oxford won't be an instant monster-science boon. I'll get the cottages back from satellite cities, grow a couple sizes, add an Observatory, and then pile on the scientist specialists.) There's one piece of bad news though.
Mackoti can't compete for me in raw tech pace at all, but he just got himself 1500b towards Scientific Method if he wants. That said, he's still racing towards Rifling because he fears he's about to be Cav-bombed. So here's my competition for the Kremlin:
REM: He could probably beat me to Kremlin, but he's not interested in obsoleting his monasteries this quickly. He looks to be headed towards Assembly Line.
RMoG: Too far behind
Plako: His golden age is about to finish, and all it got him was a scientist and a pair of Engineers, and that's not nearly enough, and he's still working on Rifling. I'm pretty sure he burned one Engineer on Replaceable Parts. Anyway, he can't beat me and doesn't appear to be trying.
So that leaves Mackoti.
Good News: He's clearly racing to Rifling as fast as humanly possible. His break-even tech rate is bad because his costs are enormous, and he's adding more military now for fear of REM. From a meta perspective, I think he's aware that if he looks like a threat for Kremlin, REM will be forced to put a stop to that. On top of all that, I think he knows he's got enough land to win if he can just hold onto it. So lots of meta-signs point towards him conceding it.
Bad News: He didn't get that Scientist for nothing. He's sitting on a treasury stockpile of 1800g. His costs are almost certainly much higher than me, and he's burning it on Rifling, but he's got the raw beaker potential. He's partial-teched Liberalism. I'm not sure exactly how many beakers he's got in Liberalism, but let's call it 500b, and then he's got 1500 potential beakers into Scientific Method with his scientist. Finally, his golden age isn't over, so I'd expect at least 1 more great person to pop out if not two.
So, take your pick. Thankfully I get to wait two more turns to make a decision, and I think I'll have a better picture then. If he continues burning his treasury on Rifling (I think he will), I'll feel great about the Kremlin chances.
What about Security?
This is the other angle of the Kremlin run. I'm currently building Knights, Catapults, and Galleons. I'm also going to tech Gunpowder first. Whether or not to delay the run to grab Military Tradition to unlock Cuirs is an open point, but I'm leaning towards no, or to compromise putting a turn into it just for safety's sake. I've got a few big things going for me security-wise.
1) I doubt Plako would attack me. He doesn't have Rifling yet, and he doesn't have Astronomy yet, and I'm about to get city visibility on him. He doesn't have enough of an edge on me to make anything stick. I'll probably flash a Galleon or two at him over the next few turns to dissuade him.
2) REM and Mackoti attacking me is not impossible, but it would be wildly risky. From Mackoti's perspective, he's already got enough land, and he badly needs me to not dogpile him. Attacking me would hand the game to REM, and he knows it. REM on the other hand has slightly more reason to attack me. He does need more land, and gaining fresh land is a valid option over attacking Mackoti. That said, he's got to be aware that Kremlin is out there, and it'll be won by someone other than him - either myself or Mackoti most likely. Given that choice, I would think he'd prefer I win it. With that in mind, I don't see why he would attack me and hand the Kremlin to Mackoti. That would seem like a mistake. RMoG seem like a better target both from a meta and geographic perspective.
3) On top of all this, I've got two explorers and a spy floating in REM and Mackoti's territory, and I'm going to use them to watch for any troop shifts towards me. I should be able to get myself a good 4-5T warning if one of them decide to punish me for a Kremlin run, which would be plenty of time to bail out and get Pinch Cuirs to stave off an attack. (And of course, city visibility on Plako should be fairly soon to watch the other border.) Don't get me wrong, that would still be difficult against Rifles, but it's plausible.
So... I'm now leaning towards Kremlin. I'm still changing my mind once per hour, so we'll see how we feel in a couple days.
Mack's primary stack (he's got plenty of other units scattered) recovering and hanging tight. I'll keep an eye on it.
Finally had a nice comparison turn. REM was running 100% science on a 1-prereq tech with no known tech bonuses, so I temporarily set tech to 100% onto Liberalism which has 1 prereq and only 1 known tech bonus. I'm behind by about 250GNP. My culture is going up, but it's still much lower than his, so I'll approximate it and "adjust" his GNP down 100 points to compensate for the culture difference. That's about 20% higher than me. I'm at 650bpt max research, and that would put him at 780bpt max research. He's got Oxford, and I don't. I dunno, I'm feeling okay about that. I don't know what his costs are, but I'm assuming it's pretty close to mine. He's ahead of me, no question, but the next batch of techs potentially favors me.
Military in most places. Masterclass whipped a Market so that I can run a couple Merchants on top of the two scientists + engineer that's currently running there. I'm going to focus on great people there, so I'm thinking about putting an Observatory in there soon for an extra scientist slot, not to mention the 25% modifier on top of Rep specs. Rage Quit is going to 4-pop whip a settler pretty soon, and it'll probably do that again soon because I've farmed it hard to have a heavy food surplus, and I badly need to fill in a few gaps to take further advantage of SoL. I just can't commit too many resources to settlers just yet for obvious reasons.
Interesting times for sure.
