A quick 5 minute search shows me that this is true. Lots of articles and lists out there. And the only games I could see that weren't sequels or remakes, are Starfield and Harry Potter.
This isn't a new development either. Pong had a sequel.
Elden Ring. Cyberpunk. Outer Wilds. HiFi Rush. Stray. Midnight Suns (licensed like Potter but original).
Not saying a lot. But far from none. And alongside Starfield and Horizon Forbidden West (second game in an original series) it’s hardly no original titles.
