AL also has the ending when you can get back with your cheating ex, never managed to get that one btw, but I was not playing with URM, or walkthroughs back then.
BUT, I think DIK will still edge out in the end, hinted MMF threesome with JB and Elena, scenes with Heather after she was shown explicitly with Tommy, multiple instances of girls(albeit background characters) getting fucked, the seeds of helping Derek get a girl, the fact that multiple DIKs are explicitly stated that have fucked potential endgame LI(Riona), hearing about Quinn and antagonist Vinny etc.
Those are all a lot of things others avoid doing and the vanilla fans dislike, but its not surprising to me here isn't that much of an uproar about it. I still think he might be the only dev that does these themes/tropes the right way, without rubbing it in players faces with constant reminisce about what the prostitutes/slutty girls do, unavoidable voyeurism scene 'its only this scene because its important for the story ' and its ok because 'the MC doesn't have feelings for the girls yet', flashbacks, videos and photos of the acts that the player should be totally ok with because 'they are in the past', you know the constant pussy dance when devs don't have the backbone to stand up for what they produce and they try to veil it.
Not sure on which side of the 'NTR war' I see him, not sure he actually cares more than being aware of DOs and DONTs of the subgenre, but its no denying that he is at least trying to push the envelope while being as respectful to the core audience as possible.
