This is getting ridiculous.
Does anyone on BGG actually not know why FFG had to retheme Dune into Rex?
If so, just search the Geek for "Frank Herbert estate " and all will be clear.
No, I'm pretty confident they know, and are just hoping that the snooty, hipsterish snark-whining will someday achieve critical mass and blow up the Herbert estate and they'll get their way.
