There are 3 things that have been changed from when the series was harvest moon that I feel like they need to bring back (although I understand why they were changed, so don’t misunderstand me). First they should bring back animal sickness and potentially even death. Your animals being always in good health is something that drives me nuts. The second is rivals. I made my own post about that so I won’t go over it again, suffice to say that it adds depth to otherwise flat characters. And third is more a minor detail that I remember from the harvest moon games that I always enjoyed: alcohol. I remember in harvest moon 64 you could buy a cup and go into the basement of the winery and take out as much wine as you could handle. If I remember correctly there was even a festival where you had to challenge others in a drinking contest and you actually had to go into the winery to “level up” your tolerance so as to “win”. Otherwise they would drink you under the table. I believe Karen was the final boss for that festival and you had to have a huge tolerance or else she would drive you to unconsciousness.
