A ecosystem where you have to shoot both bucks and does so you don't get an over population of one gender just like real life also that there are other hunting season like one where you can maybe only hunt one gender like the buck and make so that does get lam and crocs get baby crocs that you cant hunt before they get older. also there are more like pre hunting stuff like making food stands for deer or birds and renovating huntings stands (like if you don't use the one ingame then you have to renovate it to use it after a long time)
Just a suggestion 😄
