No buildings until Elder's Hut, but the Language Civic, available at Language, gives +5%
, and the Oral Tradition Civic gives another 10%.
What Dancing said though still goes, the PreHistory is supposed to be a period of blossoming civilizations with scientific innovations and population booms.
Getting a little behind does not matter, but getting too far behind early on can spell doom.
This because once anyone reaches any other era the difference in Science output is mainly dependent on the amount of science producing cities a nation has and the difference might be between taking 30 turns to research or 20 turns to research, or going 10 turns behind on average per technology.
This is a lot less than in PreHistory. Now I only compare right now with the Eternal because it is possible that other speeds do not have the same problem. On a large map on a higher difficulty on Eternal the first few (6) technologies might take 40+ turns in average, turns the AI with getting a bunch of early techs free from start (including enough to overcome negative Education right from the beginning by being able to go Oral Tradition Civic). By setting these techs back even more due to negative Education to 70+ turns (was more with 2 negative buildings) means 30 turns longer per tech, or 180 MORE turns, to reach the point where the AI started off. In effect giving the AI 400+turns to get established before the player can even start growing.
So, for OCD reasons it not looking good with a less "smooth transition" might break that part of the game for some players.
Might I suggest starting with the first negative only reducing 5%
, in effect removing the bonus for Language Civic.
The second having that and adding -1
.
The third having both of those and adding the -5%
.
The rest then maybe increasing in values to keep a smooth transition.
Cheers
