I did not really like Civ5's randomness, you really needed a perfect map (3-4 mountains to settle near), peaceful neighbours to trade gold with, etc. Civ6 seems more flexible as you do not need to really roll that 98% perfect map to have a sub 200 science victory. I end up leaving everything not related to chemistry unfilled, so the entire bottom of the tree and the bottom middle. Going straight for the space stuff. But the correct play is say a low tech costs 90 beakers, but chemistry right now is taking 2 turns. So complete the low tech, the snowball science now makes chemistry take 1 turn. So in both cases you completed chemistry in 2 turns, except now you also got a free low level tech off the table. I tried a strategy at the end of that game were I gave my cities to another civilisation then declared war and pillages the science districts which give +25 science, but they did not pop a new tech every pillage. Popping a Great Scientist (+science per mountain/wonder/rainforest) does pop a tech though. Maybe in a few days will attempt at a sub 100 and post the turn 1 of course, so others can try. This map I posted is not the best. Geneva is a must, I found that once you eliminate like 3-4 civs, the remaining civ tends to be peaceful. More critical then all this is a PERFECT early game. If you waste 5-8 turns before turn 45, you will fail. As that 5-8 turns will turn into 10-20 once the game progresses. If anyone wants to try this map. No Geneva, no super close neighbour, but it has 2 horses in capital and 2 science city states. So you do not need to build an extra settler before you can start chopping horsemen. Also the way the AI civs are spread out, it looks like you can sweep up 4 civs with 2 streams of horsemen. There does not appear to be any chokepoints. Im starting to wonder if you can just trade for the second horse / 2 horses. Then conquer the AI you traded with to control the horse.
