I like the points so far but there's some that just miss the mark.
1) You can't have your cake and eat it too, your either like voyeurism or not so if your playing for the shower scenes with the girls you can't call the character creepy. I have played the game already without peeping much and it didn't affect much if anything if I remember correctly. Stealth points have pretty little effect outside of the voyeur aspect of the game.
2) 99% of the grind is directly related to Eric, after getting rid of him the game flows a lot smoother to me. Plus a degree of common sense is reestablished.
3) And this is one point I generally try to shy away from. You can't be onesided when applying logic to a scenario even water can exist in three states and still be considered water. You can drink water but you can't drink ice or eat vapor. NTR is NTR but most arguments seem to suggest it's only NTR if it's against the protagonist here and turn a blind eye when it's reversed.
4) Not sure of this point, I'll have to go back to replay the beginning to confirm. But I'm pretty sure Eric was the person that suggested the punishment system and then later the naked punishments. If I'm wrong I apologize up front.
5) Last point, A fundamental fault of a lot of arguments. Ann, Alice, Lisa and Kira are costars in this VN. Eric is a popular extra at best. This game is about Max and constantly debating that is pointless to me. If you go to see a Spiderman movie and like Vemon more do you remove Spiderman from his movie? Guessing the answer is no. You'd make a Venom movie. I raised the problem with that in an earlier comment too. Frankly producers will produce what the majority will pay for.
Just get enough supporters together and I'm sure an Eric based game can be done, but this one is already taken.
