Except that games are not art, not in the traditional sense of the word. Games are just that games and games that contain developed narratives can provide artistic or inspired ideas. But at the end of the day like movies and music, games are products created to be sold to the consumers (Gamers) and therefore are subject to the same rules as any other product offered in retail.

Games are sold to consumers as products of entertainment and if the consumers do not like the product then the developers have two options: keep their product as is and lose business or change it to the satisfaction of its consumers to try to win them back.

Now I won't delve into the subject on how Bioware made many claims concerning ME3's multiple different endings, how this was the player's story to craft, how it was returning to a more RPG mechanic versus ME2, and then failed to deliver these under the excuse of "artistic vision". That is one of the things that ired the gamers most, the developers' claims about the game that it would be this or it would have that and then it didn't. But I digress.

Back when I played Doom 3 I remember the first mod I installed was the "duct tape" flashlight mod in order to be able to play the game. It's not a matter of ambiance where the darkness enhances the tone, this isn't a movie, it's gameplay issue because without the flashlight I couldn't see a damn thing in the game so I couldn't play or enjoy it, I never knew where to shoot or which direction to move to, everything was just drak gobs across the screen.

So those are the choices for the developers, either listen to the customers or don't. As is the choice of the gamers to then stop buying the games if they fail to meet their expectations thereby making the same devs lose their money and their fan base...but hey, at least they kept their "artistic integrity".
