They do exist and in greater numbers and variety than ever before. Play Undertale, Baba is You, BeamNG.drive, FTL, Disco Elysium, Emily is Away, Islanders, NEO Scavenger, Rodina, Whispers of a Machine, Proteus, etc.
Totally random examples, but I could name dozens more. We are spoiled with great games that are pure expressions of their developers’ visions. There are more of them than anyone can realistically ever play.
The studios who do this mostly aren’t looking for an actual artistic vision. Play any of the recent Ubisoft open world games and you see at best moments of it during distinct, isolated sections (usually trips caused by substance use) that were clearly tackled by smaller teams within the large group of developers. The rest were busy making 15 different types of trees.
