XSEED considered the names Summer Solstice, Autumn Wind, and Plow & Propose before settling on Story of Seasons
Until 2014, Natsume distributed the Bokujo Monogatari games in the west as Harvest Moon. Marvelous and XSEED then decided to localize the games directly, leading to a name change. Bokujo Monogatari is now known as Story of Seasons in North America and Europe while Natsume uses the Harvest Moon brand for new titles it develops on its own.
Before XSEED settled on Story of Seasons, a number of different names were considered. These include Summer Solstice, Autumn Wind, and Plow & Propose. XSEED revealed that tidbit on Twitter to celebrate its 15th anniversary.
