Yeah, it's hard not to consider the runaway success of games like Stardew Valley as counterexamples to the idea that the creativity is completely gone. But you wouldn't blame someone if they superficially looked at screentshots and thought it was a run of the mill retro pixel game. But it's wild to me that there are people who come from broken homes or rough childhoods who say the game was literally therapy for them and showed them a vision of domestic life or human interaction that they could realistically replicate or at least shoot for in real life.
I'm currently playing a game that is a blatent rip-off of Stardew Valley to the point where I frequently question why they were so obvious. (Or maybe those elements are rip-offs of Harvest Moon, I haven't played Harvest Moon to know.) Still, it's enjoyable. The design elements and places where it does diverge from Stardew Valley make it more enjoyable in my opinion.
As the saying goes, "good artists borrow, great artists steal."
Harvest Moon defines the "Turning round a dilapidated farm in a small village where you give everyone gifts all the time" genre. It all comes from there.
EDIT: Stardew Valley has so many QoL improvements over harvest moon though. The early HM games are punishing.
