I don't know about you but there is a small amount of fruit trees in stardew valley. It would be nice if there were more fruit trees to choose from eg. Bananas in summer, Mangoes in Spring, Lychees in the Fall
If this were to happen it would probably come in a major update. More variety would probably prompt more refining methods and more mechanics and more balancing. It would be interesting but we probably won't see it anytime soon.
I know not everyone likes/can use mod suggestions, but Longevity has a lot of additional fruit trees as well as a new fruit tree artisan product.
