The market is not impenetrable
AAA games are finished. Sacrificing fun and trying to create the next big live service job or high fidelity cinematic game. Imagine having 200M to blow and you use it to create an outdated first person game
And 18,000 games last year, but 95% of them are most likely games with no identity of their own. Especially the indies. All the Dead Cells, Amnesia, Hades, Hollow Knight, Dark Souls, Slay the Spire, Stardew Valley clones with a different paint. It has reached a point where indie games in early development get more traction than big games just because they're doing something fresh or something we don't get enough of
