I agree with you, but would also point out that the same is true for movies and books. In the general case, they're not any better off than video games. They've just both had much longer to accumulate classics and genres. You see this starting to happen in video games (walking simulators for example), and it will definitely continue.

I think you just haven't played enough games.

I won't get into any comparisons of books and games, but I can absolutely say that I have played games that, at the very least, can objectively (or as close to objectivity as you can get when discussing art) be considered good art.
