It also unlocked Bronze Working, at turn 19 with 1.5 Science per turn. They need to gather:
- ~17.5 Science into Pottery (5 turns remaining)
- 25 Science for Animal Husbandry (completed?)
- At least 30 Science for Archery
- 25 Science in Mining (completed: the Builder can put a Mine on a Hill).
- At least 48 Science for Bronze Working
In total: 145.5 Science.With 1.5 Science per turn at Turn 19, they would not reach even reach 30 total Science. This not even enough for Pottery, Animal Husbandry and Mining combined (~67.5 Science). Which means they either get luck and got some free tech in a Tribal Village, or we need to analyze more.
Either:
- They generate Science througth Combat, like a scientific Gorgo.
- Eureka could grant a lot more Science, like China, but does not explain how they get the starting tech.
- Except if completed Eureka grants the Technology!
- Something else, like Science through Production (for units, for buildings... after all, they are building there unique unique which is not a Slinger or a Warrior replacement... Scout? New?).
I really don't know. I guess it might be a "Eureka grants the Technology but you can't build Settlers" kind of ability.
