When you're playing a game, you don't -usually- see, let alone care about the underlying code, you care about what it does. At least in certain genres, the use of AI art (or worse, writing) can become obvious to the player, and it winds up breaking whatever level of immersion that existed. There's also the issue where it causes the 'signal/noise' ratio to go out of whack; Using Visual Novels as an example, the amount of shovelware has increased by at least one order of magnitude. You can still have a VN with good enough writing, that 'AI Art' can be forgiven; and some devs actually do that to get started, i.e. they are hoping the project gets enough interest and support that they can go ahead and pay for an actual artist.
