Again, you'd be a lot more persuasive if you were able to frame this argument without viewing videogames through the lens of another medium. There's no reason why they should be trying to be more like cinema, or literature. That's the opposite of the artistc integrity you claim to want.
Video games should develop their own strengths instead of trying to contort themselves into something they're not. They're interactive - when you lose the interactivity, you've lost what makes them unique, and you probably shouldn't have bothered with the form in the first place.
And I think you have a rather simplistic and rigid view of human emotional complexity. You cite works of art that inspire negative emotions in the viewer, but it's a mistake to think that you can't feel bad about something and enjoy it at the same time. Requiem for a Dream is one hell of a downer, but it's simultaneously very enjoyable, for me at least. Emotions can coexist. The idea that serious art can't also be enjoyable is pretty shallow criticism.
