I agree in principle, I would often prefer descriptions over comparisons (as a reader/discoverer).

But I believe that these comparisons work. And they work well. Otherwise they wouldn't be and still be so prevalent.

Usually they are comparisons / relations to very popular titles. If people know those titles, they immediately get a representation and imaginary picture of what the game is about.

A more direct description requires interpretation and creativity to assess, understand, and imagine.

I personally think it's better, and can spark better and more personal interest (e.g. from the example "cozy" and "power washing"). But regularly seeing comparisons tells me many others don't.
