When working in the map editor, it would be interesting if one could specify the amount of 'fish resources' on water bodies, similar to how one specifies coal, gold, iron ore, or granite resources. This would then dictate how many fish the fisherman could catch in-game before that particular area of water is depleted.
It would be helpful if there was also an 'unlimited' tag for fish (or even mining) resources, or a resource that does not get depleted no matter how much is harvested.
Thank you for considering this! :)
