There's not much too this game yet, so i'll probably wait for A few more releases until I judge the game, but my current view is that I honestly don't like using existing protagonists for porn parodies since it just feels off and generally always prefer original mc's and I don't really mind mary sues in these type of games, at the very least it's better then the reverse. I will say however that good parodies with original mc's generally give A decent reason for why the actual protagonist isn't there and maybe give your original mc something that makes him unique as long as it doesn't involve things like mind control, brainwashing, hypnosis or anything of that nature since that has been done to death and feels like A cheap cop-out without any depth. Either way i'm hoping that this will improve overtime since there's not enough Highschool DXD parodies.
