Depends on the game. I gladly paid for Monument Valley (one of the finest mobile games I ever played) but would never pay for crap like Flappy Bird.

> Mobile games aren't any less expensive to develop than desktop or console games

What accounts for that? Even discounting AAA desktop/console games, mobile games are generally expected to have less content and they're written in higher level languages.

> Mobile games aren't any less expensive to develop than desktop or console games,

This is not consistent with my experience. I suspect it's the overly broad nature that is wrong. Mobile games are usually much shorter and much simpler gameplay than desktop/console, which aboslutely are cheaper to make. If what you meant was "the same game on desktop and mobile is similar expense to make" then I agree, but you should specify those constraints as those are important qualifiers.
