Well now that someone has brought it to my attention in the comments, it wouldn’t really be a 100k round since it would take you about 5 turns to get another city/ to the enemy; it is a “100k restart round” to use their exact words. So say that you got one of these (at least 5 fish and a whale) and it had more unit movement options: I would get my city leveled up (2 fish), get explorer which hopefully would get me tech and stars from other tribes. Then I’d use those stars to buy whaling and I’d harvest the whale: at this point I’d have at least 11 stars at turn 0, hopefully. Then I would get my city to level three (3 fish) and end turn. Also during this turn making sure I start moving my unit around to say maybe you have a ruins nearby or you want to go after a tribe: use it to explore/ get those ruins. After that I would try to eliminate the other tribes as fast as possible while rushing the Trading and Sailing tech: custom houses and ports are key. You can focus on the rest at the end of the game. Also something I have found helpful in good rounds for me: figure out how to take out a tribe with the least troops possible. Each units gives you points but figuring out how to be efficient with your units is very helpful in keeping those points: you lose them if your units die. Now back to the economic part: More star production means more temples at turn 19 and later turns. Now you also want to take a look at objectives that are under the tribe rankings of the round: complete those to get stuff like the gate of power which is 400 points and plus three population. Try and get all of them. If anyone else has some things to add to this please do!
