The answer to this is “yes, but it’s complicated”, with the specifics depending on exactly what you are referring to as “Harvest Moon games”.
“Games in the series that started with Harvest Moon on the SNES”: Yes, and still getting regular releases, with a mix of original titles and remakes of the old games. However, there was a messy breakup between the developer and publisher a few years back. The publisher got the name “Harvest Moon”, while the developer got pretty much everything else, so the new games continuing the series are released under the title “Story of Seasons”. There’s also the Rune Factory series, a spinoff that combines farming with RPG mechanics and combat. It got a new release (Rune Factory 5) last year, and there are also remasters of 3 and 4 that came out recently on modern platforms.
"Games called “Harvest Moon”: Yes. As mentioned, the publisher got the series title in the divorce. If you browse pretty much any platform there are a number of minimal-effort shovelware games called “Harvest Moon”. The one coming out this week looks like they put at least some resources into it and are attempting to compete on more than name recognition, but I have no idea if it will actually be good or not.
“Farming games in general”: Yes, and enjoying a bit of a moment in the indie zeitgeist. Stardew Valley was a massive hit modeled closely on Harvest Moon, and we’re now seeing a wave of descendants arriving. This September in particular has been referred to as “Farmageddon” – the month started off with Fae Farm (lots of magic and an emphasis on co-op) and Rune Factory 3 Special (remaster of a DS farming/adventuring game), continued with Moonstone Island (farm, explore, and collect spirits to use in card-based battles) and it ends with the new Harvest Moon (already mentioned) and Paleo Pines (befriend dinosaurs to help work your farm).
And on the original schedule, My Time at Sandrock (crafting rather than farming, but still in the same genre) was supposed to come out today, but it got bumped back to November to get out of such a crowded release window. So you can remove it from the release list for today, but also the price is going to go from $25 to $40 at release, so probably good to buy now if you want.
And not relevant to this month’s releases, but if you want to play an indie Harvest Moon descendant in active development with “very positive” ratings, you have your pick of stone age (Roots of Pacha), fantasy (Sun Haven) or tropical/mermaids (Coral Island) flavors.
Actually, do we have a thread for so-called “cozy games” (the catch-all term that gets used for farming games and their relatives)? I keep an eye on the space because my daughter is really into them, and enjoy them from time to time myself as a nice change of pace.
