Love the mod. Just an idea; the ability to change the yield from 100% to something else. This would increase challenge for me as I could change it to like 50% and still have motivation to seek out many resource patches.

Anyway thanks again for the mod, love it as is.

I think my philosophy around being able to change the yields is that you should just adjust the map generation settings to make ore patches larger/smaller and more/less frequent. It's not quite the same thing as what you're asking because a constant yield means that each individual miner will always produce at the same rate, but I like the simplicity of it. Reducing the yield to 50% has the same overall effect as reducing the patch size by 50%, but you just have to use more miners.

I hope it's not out of line for me to recommend my mod which supports the feature requested by Makanikai: https://mods.factorio.com/mod/yield-ores
