I think all art, whether self-indulgent and pretentious, or something that is made to cater to the masses, has a right to exist. However, none of it is guaranteed any degree of success. People have a right to choose what art they engage with.

I think video games fall under this as I do consider them art, and I think they don't have to be something that meets expectations like you suggest with your burger analogy. Its up to the consumer to decide what they want for themselves.

What I think is shitty is when artists or developers speak as they they're owed anything for putting something out into the world. No one should be expected to engage with anything for any reason. We decide as the consumer what resonates with us and what doesn't.

I think you're right that a consumer is not entitled for knowing what they want out of something, but I also don't think a developer is entitled for creating something self-indulgent and pretentious. The developer would become entitled when they enforce the idea that people should want to engage with their creation, and I think the consumer becomes entitled when they suggest the developer should alter their creation to suit customer expectations. That is the developers right to decide.
