I hear this often come up in this kind of discussion but personally I think I tend to the opposite, to have higher expectations of things I pay more for and judge them more critically. It might align with spender vs saver mentality (and granted the bulk of game buyers are spenders by simple statistics).

Would be interesting to analyze but hard to separate from complexity. Although there is an inversion at the upper end, comparing $150 heavy euros to $400 thematic miniature extravaganzas (which tend to a middle weight).
