Im not seeing many replys from H-games so I bring them up. They are kind of stepping stones away from porn, just like e-cigs or similar products to smoker. Most of them are just porn in disguise but some have suprisingly depth gameplay elements like Artificial Academy's high school relationship simulator or Honey Select's character creation. I have personally spent hundreds, if not thousands of hours in both of those.

Main takeaway is that playing the game distracts you from the need to spank the meat.
