What if maps generated areas (around rivers or valleys or whatever makes for interesting strategy) that are considered fertile.
These patches of land don’t do anything except providing a bonus to farms established in them. This could be either cheaper to build a farm on them or faster gather rate or both. This could make for fun and thematic strategy for controlling territory to be able to have “super farms”.
Its an interesting idea but it would require relic to really balance their map generation.
It could also lead to some civs (like the english) being superpowered due to their already existing farm bonuses.
I like this idea. It’s a good one; adds a lot of strategy if implemented properly.
Since this is surely never going to be implemented in AoE 4, I recommend you go and grab any of the Anno games, which do mimic this very same mechanic. Almost all of them are great games.
