Asoka is down, but it took longer than i had hoped. I took two cities on the first two turns of the war, but he got rifles the turn after that. I basically spent the next dozen+ turns trading units with him and trying to pick off anything in the open while my cannons arrived. Better unit management could have saved me numerous cavalry too.
Something else pretty big happened during the war.
Zara declared war on Lincoln. This has the potential to be very good if it slows Zara down, or very bad if he rolls over Lincoln and capitulates him. A few turns into their war Lincoln lost a city at which time i noticed he didn't have Rifling yet, so i gave it to him on the cheap to defend himself.
I should've seen that earlier, so that was a mistake on my part. Hopefully Lincoln didn't lose too much of his stack there at the start. He hasn't lost any more cities since, so I'm crossing me fingers that one turns into a nice stalemate.
Meanwhile, enough of my cannons and redcoats caught up to finish off Asoka and nab some really good stuff. I did leave him one city rather than kill him off b/c he has several techs that i can still use.
I've identified logistics as the biggest hurdle to winning this game right now. I can overcome Zara with a bit of a tech lead, but only if i can get my units to the front in an efficient manner. Therefore I've decided to go straight for RR to set up supply line. I'll have it in no more than 5 turns. I have 13 workers right now (could've sworn i had more) that i need to start getting into position to build the RR line. I may need to build a few more here before RR finishes.
I was also considering going for Combustion next for Destroyers and Transports to cut across the sea, but i noticed there's no good source of land oil without taking out Lincoln or making this insane trade with Joao.
Perhaps it's better just to go on to Arty followed by Infantry. I think RRs will provide fast enough transportation for my units without the need for ships. It's exactly 30 tiles (3 turns) from my HE city to the Roman-held city of The Hague on the Dutch front, and 40 tiles from my furthest city. It's about another 20 tiles to Lincoln which is still very doable. By the time I'm ready to take on Zara I'll have Oil.
I'll get Communism from JC in 6 or so turns, and I'm hoping to start a 12-turn GA in 10 turns providing that great person doesn't pop as a GS.
Edit: Just noticed that Portugal can research Plastics which means he already has tanks and marines... fantastic!
