Even before AI you had a swarm of slop clone games. Half of steam and itch are "indie" games with are just absurd slop or a game clone.

And still, these games won't be played or take up the same space that the originals have in players minds. I'll enjoy playing GTA 6 - I won't enjoy playing Vibe Car Theft 6 which emulates it. Especially in indie gaming, where people relate to the creator and choose to support them.
