Hey this is a Marcus alt!
I have alot of suggestions in the work but I am really excited about this one and want to get it out there!
Okay to break it down my suggestions is that all characters have another way to make money. Raising crop or cattle ect.. would be a natural way to live in a real world Arda so I have come up with a way to do that. The only way I can expalin this is to show you my version of this system that of which I encourage you change to fit Arda in the way you want to!
There would be a shop called the Rancher or ranch Shop there you are required first to by either a ranch a farm or a garden. then you must purchase an item that can go in your specific ranch, garden ect.. You plant or allow the creatures to breed. Then in the alotted time for that crature a new carrot, calf ect... will gow. Now you can sell that at market and maybe eventaully it will become part of the slughterhouse (another suggestion of mine)
I took the liberty of creating this shop maybe to ease ya'lls work. These are the images i could find in your current shops and edit slightly. Other than that I couldn't find more but maybe this will give you an idea or what I mean! Hope ya'll like it!
