Ethiopians receive a bonus of 100 Food and 100 Gold upon advancing, while Dravidians get 200 Wood.
These bonuses are beneficial in the Feudal and Castle Ages, but become less significant in the Imperial Age.
One idea to improve these bonuses is to change them to “100 Food and 100 Gold per Town Center” and “200 Wood per Town Center” respectively.
However, this change would only come into play after reaching the Imperial Age, as players can only build one Town Center before the Castle Age.
To prevent excessive resources, there would need to be a limit on the number of Town Centers (e.g. 3 TCs).
Overall, this change has the potential to make the bonuses more substantial, granted the player is able to build additional Town Centers.
