Games are not an art form, they are games. They would be an art form if the player was just a recipient, not a participant in shaping how it all turns out. A work of art is finished when it gets to its recipient, whereas a game will only begin at that point.
Games don't have to have any story (think poker, chess, or a million others), but if they do, they can potentially be superb at it. Think of BG2, PoE or Deadfire. For me, the excitement of those games relied on the story. Nothing against the battles, gaining XP and all that, but the story was the main thing. This is demonstrated by the fact that once I played the game to the end and knew the story, much of my interest was gone. I don't replay much, although it does happen.
The storytelling in the games mentioned above is not particularly great if you compare it to good literature; it is somewhere at the genre fantasy level, I'd say, but the fact that you can shape the story makes it more interesting, to me, than reading books like that, which I never do anymore.
I'm all for games with (hopefully good) stories; in fact they tend to be the only games I play. Disco Elysium was a very story-heavy game, and it's the most enjoyable game of these recent years for me. I think it's just wonderful. It didn't matter one bit that there wasn't a single classic battle encounter in it (or perhaps just one, if you count that one thing...).
I am very excited about Pentiment, which I haven't played yet, at all, although I installed it yesterday.
