Well done!
All of your research comes from Sushi-powered Representation Scientists, right?
Regarding the strike, how many units do you lose per turn? I'm guessing that you use work boats or is it some other unit?
Knowing the power of Sushi, would you still found Mining before Sushi? Or would you do it the other way around? I always felt that Mining first was better because those extra hammers make spreading Sushi easier/faster.
Not too shoddily played, I believe. I was rather impulsive, if not downright hasty, on several occasions. There were miscalculations. For example, I got wrong value for Composites and noticed it only when I could not do Ecology in 1 turn. Did not make any difference in the end because then I did Genetics in 1 turn, instead of 2 turns as I planned, and there still was about 8000 beakers overflow.
Mining produced 8466 hammers (9906 with multipliers taken into account).
Average population from Computers to launch was 1559, most of them scientists. Since most of the cities with Sushi had libraries and some also had observatories and labs, average multiplier was probably about 1.3, which brings scientists contribution to roughly 12000 bpt.
Workboats in neutral keep executives, missionaries, explorers and workers in my culture alive, and ships with these units are also safe. This makes workboats perfect sacrifice to keep late game spreading on. I did final Mining spreads on t305. That turn 21 units were swallowed by the strike monster, so this turn cost me 1260 hammers worth of workboats. Three executives and the gold cost 753+ hammers. That was 317-305=12 turns before I finished research; that's 3*51*12=1836 hammers. So it almost entirely covers the expenses and workers had one more turn to build improvements.
It is hard to make Sushi stronger than 20 food early, while mining typically starts at 35-40 hammers and quickly gets to 45. Besides, the benefit of Sushi is delayed and you need Kremlin to make the most of it; getting enough overflow for executives without either Mining or Kremlin is excruciatingly difficult (and I did not put it this way just for a want of a fancy word). That is Mining is just plain more powerful until certain point. So, its definitely Mining first. May be, if you go for early Communism...
