and there's a difference between reading someone's story of what actually happened and playing it and I hope you'd know the difference.
And here's why our medium isn't even taken seriously by the people who claim to enjoy it. It's okay for books, or movies, or graphic novels, or music to focus on real life war stories, but if there's a controller involved, suddenly it's gauche. This is the exact dialogue that says video games are not a meaningful form of expression, and not a legitimate art form. The problem is that they are art, and they can express the thoughts and feelings of the situation just like any medium.
You're right in general, but if you think yet another game where you are a badass white bro gunning down hundreds of brown people single-handedly is actually a meaningful expression of anything (other than the unquenchable thirst video game enthusiasts have for jingoistic power-fantasy murder porn) then I don't know what to tell you.
Video games are absolutely a legitimate form of art, it's just that very, very few developers bother saying anything worthwhile with them.
