Could it be due to HN being more PC than console? I personally have not played Harvest Moon and am only vaguely familiar with the name. Stardew Valley however runs on Linux and has a large mod community (Stardew Valley Expanded for example) which has ensured a lot of replay in our house. It's the preferred family coop.
All the games mentioned in these comments are great, anyway. And I found some new ones to try now. :)
