Which imo this is perfectly fine. Games running in RPG maker are almost anyways an instant pass unless it focuses exclusively on the exact things I am looking for (so unless I decide to commission or created one, is almost certainly zero). Having you fight monsters, maintaining an inventory system with weapons and health potions, is not what I'm looking for in a porn game.
Even the most ambitious and well done games like Carnal Instinct has me thinking, "I'm spending a lot of time running around a desert and not much time having sex". And in WVM, I'm thinking, "I'm spending a lot of time looking at the faces of characters I can't even remember the names of, reading a lot of 'plot' and bad dialogue." I'd wager that most people would rather have him remove a lot of characters at this point, instead of adding more.
