Flawed Logic
I agree that enterainment can be mind numbing, but brain washing is flawed logic. Brain washing would be intentionally trying to change our way of thinking to theirs, and typically for a larger entity, like the government, or any sort of belief system.
The idea of making games for people to enjoy, and want to play non-stop, and think about while they're living their life may be destructive to the idea of creation, or productivity, but it is NOT a malicious scheme to get us all thinking the same way.
The implication of the logic would be that any art, or anything that affects someone is unhealthy. And in that case, if this animation ends up making people agree with you at all, then YOU have "brainwashed" them, by your definition.
I appreciate the art, and the style, and the well displayed train of thought, but the framing of the argument, as well as the narrators character seemed to be out of place for what you were going for over all.
