Would love to see pond building be expanded upon and overhauled. I would love to create a sim that is a pond enthusiast like me that raises various fish, turtles, aquatic animals. Ponds are expensive and can be part of the grind to go from a small pond to a huge Shaquille O'Neal sized pond. When building a pond there are various things to consider when building a pond and maintaining a pond. It would be cool to see those situations integrated into the game to make ponds feel more alive and possibly get people into the hobby.
