Friends of mineral town is basically a remake of the ps1 game. The only difference is thst instead of having 3 years to bring the farm up to a certain level, u can play this game for as many years as possible. Theres in game achievements for playing it along time. Friends of mineral town adds beach villa and beach houses to own and it adds more animals to lool after which is really cool. Havent played Olive town but reviews say its amazing
My understanding is to just avoid everything published by Natsume under the Harvest Moon name after 2014. Those are done by a different developer and not very good from what I hear.
