Gen 5: With 43mc in hand I would immediately pop tech demonstration and search for better cards. And who knows, maybe the opponent might raise oxygen and allow you to play methane from titan.
Gen 6: Domed crater location is weak-- you're putting it there for pretty much the card and mining area purposes only. I would put it next to noctis city and then use mining area. Then you have 4 other nice conversion spots available next to the city. I don't think the card is critical.
Gen 7: I would not keep fueled generators, ants, or heat trappers. With peroxide and biomass in hand, no more power is necessary (especially without any power targets). Ants is a threat against decomposers, but decomposers is already in your hand. Heat trappers is too late to be effective at this stage. Also, why play ganymede colony instead of methane from titan? Methane from titan is much better production. I know the milestones are there, but with the game progressing at this slow pace (temperature still at -28) the milestone points are not as critical. Also, you can just SP city next generation (it only costs 18 for you) on the east to claim mayor. Hackers gen 7 is not worth it, especially when you need to play fueled generators to do it.
Gen 8: Fusion power is nothing but an expensive science tag. I prefer picking mangrove, even though it is far away. SP oceans is inefficient, and you don't have algae or kelp in hand to work towards. I would just play methane from titan.
Gen 9: Beam from a thorium asteroid is too expensive. 27 MC for 2 points (and the production is almost meaningless now, maaaybe 1 heat bump). There are more important cards to play in hand right now (looks at methane from titan). Or you can SP two greeneries for the 8% oxygen bonus, which only costs you 24 MC (bless credicor) and gets you 3 TR, 2 points, 3 plants, and brings you closer to livestock.
Gen 10: Why not play livestock at the end of the gen?
Gen 11: Trans-neptune probe is superior to robotic workforce at this point. The production does nothing while a cheap point is appreciated.
Gen 12: It looks like the game is ending this generation, so grass really doesn't cut it (especially when you already have so many efficient cards in hand that need to be played). I would even be hesitant to take kelp. Your current hand has:
Robotic, quantum, Antigravity (33 for 3 points + discount). I think that is way too expensive to go for.
Birds (8 for about 2 points)
Imported nitrogen (12 for 4-5 points. You slept on this one.)
Imported hydrogen (9 for 2 points)
Mangrove (8 for 3 points. Another very good deal which went neglected.)
Interstellar colony ship (13 for 4 points)
And others, such as insects, nitrogen-rich asteroid, which may be worth it if you somehow still have cash remaining. Kelp meanwhile is 16 for about 3 points, which compared to the rest looks pretty bad.
Magnetic field dome is not worth it.
At the end, nitrogen-rich asteroid is not efficient enough (19mc for 3 points is worse than the above). Just use your hard-earned heat.
If the above calculations are too much to do real-time, you can save time with some intuition. My intuition told me grass cannot possibly be worth it at this stage. For kelp, I would compute it is 16 for at most 3 points, and our hand just looks like it is already chock full of efficient points, so I would not keep it based off that reasoning.
It is also worth noting many of these cards’ points come from the TR from a greenery. Therefore they lose value if you stall and let your opponent take the TR. You have a few cards that would appreciate a gen 13 (namely antigrav), but going gen 13 would mean giving away a lot of free TR to the opponent. With your extremely efficient scoring in hand, you should be confident that you will win this generation.
------------------------------
I think overall you overvalue energy production late in the game and made some suboptimal overkeeps. The domed crater position also really hurt, since you got cut off from all the ocean rebates later in the game. (Some well-timed SP greeneries or cities would have gotten you out of this situation also.) Still, nice job on the win!
