People keep mentioning food, food for armies, food for horses, food spoiling, but they are forgetting a simple fact that the AI, at present, can't even handle non-spoiling food without starving, these mechanics, unless the AI is significantly revamped, will only make the game far worse at present.
In addition, should this be a priority now? Or should it be revisited after the dev team has actually introduced critical/important features? Right now, this will do nothing but break the AI even more than it already is, and it's obviously extremely debatable if it would really offer anything, even if it works with the AI, in place of other features that could make the game more fun.
