It is about entitlement. In your second sentence you present the straw man that you shouldn't be made to spend more on a game than you want to, but that's not what your post is really about. Your post is about how the publishers are charging too much for the game because of how little you value it. You demand that games are sold well under what any reasonable person would say they are worth, because of your fucking backlog? You don't have time to play a game, so it should be sold cheaply enough that you can just buy it anyway and not play it? You just want to have your cake and eat it too.
This sale was still amazing just like every Steam sale. Having slightly less steep discounts than a previous sale does not make it "lackluster", nor does your nonsense logic about why games should be discounted.
