As a project manager (well sort of, but did IT projects for a while, have multiple friends in the gaming manager): Yes and no.

From my point of view: The problem isn't the fact that games are art. While games have their creative side they also require good "brick and mortar work" in the back - as many games as went horribly wrong due to a lack of space for creativity went wrong due to a lack of "less than glamorous" brick and mortar work and overcreativity. (Most drastic example would be the reddit dragon MMO story)

This is actually a reason why people who are very invested in the subject matter of the project they manage often are horrible project managers - and vice versa people who have no clue can't be good PMs either.

Project management has one core component: Knowing when to ask whom. A good PM knows that the dev(or dev team lead) will always know better how long "feature X" will take. Of course I can try to learn how to do things... but that wouldn't help much as the exact dev or team will still have their individual speeds. But a good PM also will know when to ask someone else who is nore knowledgeable for advice or to confirm things. (I literally had an Dev trying to tell me a small feature would take two weeks. Fair enough. But interestingly enough two other Devs were fairly sure it takes 30min including documentation. Which sounded way more reasonable. Turned out said Dev always tried to pull these stunts with new PMs and his lead being on vacation)

A good PM will also know when to give people space for creativity - and defend this room towards the budget.

Sadly - and this is a problem existing on all sides around PM- in the end it all boils down to a simple thing: Everyone thinks they know better. The PM thinks they know the job of being a Dev(or engineer,etc. etc.) better than the actual people doing the job. And vice versa the Devs think they could do without PMs (they can't for larger projects it's impossible, for mid size projects often really inefficient) or know their job better.

Such is life.
