Perhaps that's the intention to get cum brain out of your head and then become a philosopher and get all the other endings that require more effort, especially the love endings. (Which to me are the canon endings. Yes I know its cheesy but idc sue me)
The reason JSK doesn't do sequels is because
there are no canon endings to his games.
That beign said, Love Ending is definitely the ending you should get last.
Endings are ordered in the menu in the order that he expects you to get them. Easiest -> Hardest
Rape End, Lewd End, Slave End, Love End.
Rape End you have to rape the girl a bunch of times. Be an asshole. Easiest ending to get.
Lewd End, you rape the girl a bunch of times. You have to pick the correct dialogue about her being horny or lustful, and you have to make her cum in the endings. It's Rape End with a bit more effort.
Slave End, you actually have to play the combat section well, and NOT rape the heroine. Usually you have to lose in the last round, and choose the correct dialogue.
Love End, you play the combat section well, don't rape the heroine, pick good dialogue options, and win all rounds while keeping the total damage you took throughout under a certain number.
The "best" end usually takes more effort to unlock, much like missionary pov, that can only be unlocked in the good end route.
Agree to disagree.
I prefer female assertive content so I like the cowgirl endings the best.
That being said, it seems like JSK is changing on this.
His older games were always, Love End = Missionary. Not anymore.
Magical Girl Buster Reinforcements, has the Slave End be missionary.
Love End being sitting position (lotus).
Senpai Kouhai and Gifted Ojisan, the threesome game, has
"Love" end be cowgirl.
As the Champion has the Love End be sitting position again.
You get missionary in that game from the Rape end.
Newest shoplifter game doesn't even have a missionary ending which is kind of funny. It has something really close with the standing carry scene in the love end though. Last shoplifter game was literally all missionary endings. Every single one so maybe he's just trying something different for this game.
No one said being a good guy will be easy. Much like the Law and Chaos points in some video games works.
I feel like in the context of JSK games, people will want to be the good guy on their own. You don't have to incentivize people to get the Love End. That's the player's natural inclination. But the heroines will kick your ass, and you won't make good progress just bashing yourself at that wall for a while. You can still do it, but the game's punishing you for trying for it first. It rewards you for raping the heroine so you have incentive to do that.
