Harvest Moon: Save the Homeland and Harvest Moon: A Wonderful Life were both PlayStation 2 games that had their share of issues.
More than likely Harvest Moon: Save the Homeland and Harvest Moon: A Wonderful Life Special Edition would be PlayStation 2-on-PlayStation 4 rereleases.
These would be the first PS2-on-PS4 rereleases for Natsume, and hopefully, it would open the door for more PlayStation 2-era Natsume games to be rereleased.
