I can't give you precise calculation. But if it feels like spanking is the fundamental principle of your world and it has nothing more to offer, it gets tedious really quick. Unless it's a quick game to finish in 15 minutes, you should think of it more as erotica than porn. Build-up should become vast majority of the time, and not every fight being about spanking, every mini-game about spanking, every dialogue about spanking etc. etc. Regardless of the genre of the game.
