In my current game, I started on the same continent as Teddy Roosevelt and Victoria. They both declared a surprise declaration of war, Teddy earlier in the game and Victoria later. I believe they both complained about my small military. Teddy evidently found a Relic in a Tribal Village and I made peace with him for the price of that Relic very early (before I had any Temples to showcase Relics. Victoria attacked with obsolete units; She attacked with Warriors, Slingers, Heavy Chariots, 2 Catapults, a Horseman and maybe a Swordsman. The Catapults never survived to fire a single shot. My government was just changed to Theocracy at the time and I had over 5000 faith. I simply built a Conquistador and a Missionary in each city Victoria threatened. Only her Horseman managed to kill an Archer outside of a city. It took a long time to wipe out her attacking units that were in full retreat. Next, I captured each of her three cities. I definitely should have allowed her to keep London or Liverpool, so she could continue to send me tourists, but this game was no longer in contention for the lead and I wanted maximum revenge and besides she would continue to harass me forever. Leaving her Liverpool may have been the best option, since London has proven to be a very good hammer city. It also proved to be the only place where Oil was found on my continent, not including some found off shore near one of my cities.
In any case, my continent was very rich in Stone resources (at least a dozen) and had maybe 5 marble resources, so I'm glad I picked the Pantheon belief that provides 2 faith per turn for each quarry. All my games had a significant amount of Stone resources, but not nearly as much as in this game.
With so much faith, I could have easily recruited a great prophet with faith, but I thought some civic or technology was needed to do this, so I quickly lost out on getting a Great Prophet. I suspect that the AI Civs buy their Great Prophet with Wealth of Faith as soon as they are able. It seems that the first Civ to get Stonehenge it usually the first Civ to recruit a Great Prophet.
I moved my Conquistador/Missionary pairs to the other continent. Settled two cities east of Frederick, who early on wiped out Norway. I researched to Steel and built about 6-7 Artillery in those two cities with Faith. I easily took the old Norwegian capital with Stonehenge and The Oracle. I had easily 4-5 times the military needed to capture that city. Frederick had a Knight defending in the city and I wiped out a Musketman blocking my way on the DoW turn. Frederick had a Field Cannon hitting the same Conquistador, but I captured the city and moved the serverely damaged Conquistador to safety. The AI doesn't upgrade its troops as it should. The Barbarians were more challenging, hitting me with several Musketmen and a Field Cannon just east of Frederick, just as my Conquistadors arrived on the new world. Frederick's defense later was pathetic in comparison.
I will complete Combustion, improve London's Oil, and start producing Tanks in a few turns.
I currently have the most domestic tourism. Frederick's foriegn tourism is twice mine, but that won't last long, after I capture his best cultural cities. I will avoid taking his capital, since that would leave only Montezuma with his capital; I don't want to risk an accidental Domination Victory.
I'm actually now leading in every victory condition, except Religious, where I am in second place.
I'm having fun as time runs out on this gauntlet. I may still try a few Tribal Village -> Relic attempts to challenge the better results here. I still have a lot to learn about Civ VI; I played only one game of the original Civ V, so I have only my Civ IV experience which doesn't apply either Civ V or Civ VI very much at all.
I am liking Civ VI much more than I thought. It still has numerous balance issues, but if the developers address these issues, Civ VI might become a really good game. The 1UPT is still a big issue. The AI Civs and CS generate so many units, they often block my scouting units. Corps and Armies try to mitigate that by permanently combining 2 or 3 units into a single unit, but it is too little (stacks of only three combined units) and too late (the unlocking technologies are far too deep into the technology tree).
