That makes no sense. If they were inherently worthless then no one would pay to play them.

You mistakenly conflate cost to produce with value to consumers. Obviously the content has value to consumers.

Unfortunately "worth" in any functional sense is defined by the demand for it, so in that sense these are immensely valuable. That is my lament, that something with so little functional utility (outside of a dopamine reward loop) has captured so much voluntary worth.
