Well, simple games are like simple procedural generation, just like how procedurally generated items all feel the same very soon every game of chess feels the same. To some they don't care about that they just want to play the same puzzle over and over, each chess board state is like another sudoku, to others they just want to consume more content designed by humans and then you need more elaborate rules.

To the ones who want human designed things chess is like this vast procedurally generated forest that just has trees everywhere with different branch layouts, so you have to climb them in different ways.
