Ok, here's what I think I'm going to due:
1) Setup the Hunger Mod thing like the City RPG does and get those events put in the system.
2) Get a GUI To sell and buy food
3) Make events to add to the food to a database, and decrease food from the database. The database would be like the Cities food storage.
4) Get models for crops with the events built in the brick. Like the JVS.
That's the best I got for this. I might make a plate to put plants on that lot only, but that's theoretical. If I do make this kind of lot, it will be with an update once the real estate gets out. I might make decals for this too. And I'll will make the farmer job. But, I will need help with setting that job. New items and that will be with the job.
As far as cattle go, I don't know if I want to make a different cow model, or if I want to use the existing mod for the cow, but just make a patch to make it compatible for this mod. A pig model will be made, but I don't know how I'm going about that, because of... well... you'll find out. The animals will not come out until I find out how the Hunger mod lets you gain food by killing animals.
