How to use this answer
Choose a platform on the assumption that saves remain local until first-party store features say otherwise.
The answer is scoped to Harvest Moon: Echoes of Teradea and the public evidence available on 2026-07-29. It does not import schedules, values, controls, item data, or progression rules from an earlier Harvest Moon game.
What remains outside the evidence
A simultaneous release does not imply shared progression or transferable saves.
If Natsume, a verified platform storefront, or reproducible launch-day testing supplies the missing field, this page should be updated with the exact source and review date rather than silently replacing the earlier status.
