Things seem very grim for me around T225. Spoiler : I've still only met two AI. 22 city Churchill and his vassal Monty. I do have Steel, Rifling, and Astro now, but I'm probably just about out of the trading game going forward unless the other AI are further behind. Churchill looks like a monster right now though, and I don't see how I can ever get in a position to beat him, even if i manage to take out Izzy. I just needed to meet people earlier to trade for things i ended up self-teching. I might give this one another shot going for Optics, but i dunno.
