1. Make the defense tower shoot grasshoppers. They get really annoying and eat almost all of my grain.
2. View models. I would like to see the hammer, fishing rod, and all the other tools/weapons in my hand when I use them.
3. A combine. a slow car type thing(maybe being pulled by horses) it will destroy any grain it runs over and pick up what gets dropped. Would be good for large fields.
4. animations for the opening and closing of doors/gates.
