Additional planned improvement now to be the inclusion of various era's resources per leader as well as including exploration and modern era civs, now that I know how to limit things per era as well as enabled mods

Latest update to split up the antiquity civs seems to have resolved era transition

Ah, thank you, will fix that parse then

It appears that the update today has caused the game to start normally in Antiquity but attempting to start a game or progress a game beyond the first era results in a Content Validation Failure

Gotcha, will work on that

Unfortunately, it seems like this mod requires owning all the dlc. Would it be possible to get a version that doesn't have that requirement?

"Standard" start generates the map first, then places the players

"Balanced" start places the players first, then makes a map

this effectively means that standard will put you in a good spot if there is one, but balanced makes a good spot for everyone

When/if I can figure out the controls for additional things like boosting resources or even flat tile yields themselves, I'd like to further improve it by giving all empire/leaders their own collection of desired resources, balanced over the whole biome/resource array, but I haven't found a good source on non documented, but still usable, features like civ6 had, where you could boost weights of most things the map had to offer

Talsorn, in Civ 7, the game first decides upon starting locations for all Civs and only then generates the map accordingly.

My rough understanding is that the game gives a score to each start and tries to balance everyone's score. Starting bias is not the only consideration,I believe that proximity to other capitals also matters.
I suspect if you increased the start bias by 10x then the game will strongly favour getting your desired terrain, and care less about proximity to other players.

So a "un-demanding civ+leader" who isn't bothered about their start might get shoved in a bad spot, to make room for the greedy start biases. So it's not without downsides.

It's difficult to be more specific regarding what the mod does as the exact impact of the scores are not known, but for example, it increases the weight score of navigable rivers for Egypt from 20 to 150, which has tended towards improving the starting spawns for all empires relating to their civics, masteries, and unique improvement/wonders. In another example, Aksum received a starting bias for , when their unique improvement requires flat terrain. Essentially, every associated terrain, feature, and biome has been accounted for and given a weight between 50 and 150 to improve starting placements, where normally those weights are 5-10 or

Could please provide a more detailed description for this??
