I'm aware of large AAA games taking up that much space (Doom Eternal, Red Dead Redemption 2) but they could hardly be considered "simple". Do you have examples of what you're talking about?
NBA2k is over 100GB. Sports games seem to do this a lot. It’s obviously due to the art assets that AAA roll out but there’s gotta be some way to trim the fat or at least do it incrementally.
“Simple” was probably a bad choice of words.
