Standard Immortal on Continents Plus with Arabia. Game Lost (Retired) on Turn 374.
Probably my last game for a bit (I've played ALOT lately if you haven't noticed

). Went with a 4 city Arabia (got to 5 cities once Korea got uppity and I took one of his key cities), with the plan for CV.
Ultimately I played about the perfect peaceful CV game. My capital was paradise on earth, I had TRs flowing continuously with tourism. But unfortunately India was the culture leader, on the complete opposite side of the world, and would not open borders, share religion...and I had no coastal cities to send a TR to him (which honestly I probably would never have done anyway, sea ITRs are way too vulnerable when you are playing tall, you just can't afford the navy to protect them).
I made a late game push to finish CV but India got to the Great Firewall...and at that point I knew I had to change gears. One of Arabia's greatest strengths is their flexibility, even though I had committed to a CV I still come with a crapton of science, and so I pushed hard to see if a SV was still in the cards. I was able to get Hubble, but India got to CERN first. So....that plan is out. So I tried a last hail mary. I built 10 xcoms and tried to see if I could slow down India with surgical attacks.
Honestly I did about as well I could have expected. I cut all of his major rail lines and managed to take out 7 aluminum and 7 oil. The xcoms immediately died of course...and his own xcoms retaliated. The end was nigh, so I called the ball. Ultimately this is the failing with going true peaceful TALL, when it works out victory feels very easy, but when it doesn't its hard to project enough power to affect the final outcome. My mistake was not recognizing India was going to be the guy late game (and that was pretty clear by the midgame), and adjusting myself to counter knowing that CV without warfare would be difficult. My notes:
1) Maya got uppity this game so I had some fun with nukes. I've tried to stop thinking of nukes as special (aka the horrors of real nuclear war) and just see them for what they actually bring to the table. In a defensive war, the A bombs greatest asset to me is laying fallout on the enemy's battleground. This hinders their movement and causes general damage, its very powerful if your goal is to hold your line. Otherwise, I generally want to hit with 2 A bombs, as 1 alone won't really kill anything.
2) Got to try out the GDR right at the end. They don't have armor plating which I'll note. the GDR lost 3/4 of its health guarding my front and then died to a plane attack on the second round. A poor showing indeed. I always like to remember that 2 of these guys is basically the cost of a nuclear missile (or a spaceship part if you factor in the spaceship factory). I still don't think they are strong enough. I should be terrified to see these guys on the battlefield!
3) The new tanks and modern armor are doing quite well. I am using infantry less overall but I am not ignoring them, so the balance feels pretty good. Bazookas do deal alright damage to them, so they are a threat you can't ignore.
4) Still noticing that embassies are taken less often than they used to...did something change there?
5) Finally got a defensive pact this game! I think because my civ is so small, the AI thinks my military is quite strong, when realistically this is the weakest military I have had in 5 games...but the other games I've had double the cities.
6) Honestly I'm not sure if Great Musicians are even worth anything anymore. I found the tourism bombs even late game pretty underwhelming. Anyone else have similar experience?
7) First Tall game I've played in a while where I did not have permanent GAs, and I even had the +33% bonus Great Artist resolution AND I had an elephant luxury (which is longer GA lengths). That was surprising to me, so GAs maybe more precious now than they used to be.
8) I tried out the Mastery religious belief (its been a while since I used it), and I personally think it underperforms. Follower yields are stronger earlier, and buildings tend to have scalers that help more in the late game. Mastery doesn't really do anything that I can't do better with a different belief.
