As per another comment I made here, people develop a tolerance or even appetite for complexity. I've actually played some games hundreds of times and still found nuances in the strategies. Simpler games tend to be "solved" much more quickly. What's more, absorbing and internalizing new games is a skill and you tend to start recognizing game mechanics from other games. Lastly, I wouldn't put any of the games on this list in the "heavy" category.
