Wow! You wiped Rome out in TEN TURNS?

Nice things!
So, that means... No, it can't be... I'm up AGAIN????
One day round??? You guys are insane!
By no means I can play. Nor today, nor tomorrow. So, if you feel like it, Mice, go ahead and grab it.
I couldn't see the save, of course, but the natural choice now should be crushing Ragnar. Buuuuut, he is allied with Kublai. Neither of them are easy, so I'd just declare on Churchill if no one minds, and bring the AI's with us. With pillage money, we should be allright until the game ends.
Revolting to Police State means we have the Pyramids... Nice!
What I think that can be done: If needed, switch to Universal Suffrage and shut off research. Buy a round or 2 of cannons and declare. Set research to Steam Power and later to Railroad for the draftees from Madrid, even if they are grenadiers, to arrive faster. Settle the GG there and

everyone. The only flaw is against cavalries. As long as our opponent doesn't have them, we don't need Rifling.
I think it's true, but someone else can confirm: Redcoats are not Rifles, so Grens take no advantage against them.
Good luck!
