For NTRPG 1 I'm mainly talking about the cameo of Tiris & Eric (+Leon) in the sequel. The Tiris who appears in NTRPG2 is subtly different from how she is in the first game, in that she lost pretty much all resistance to perverted acts and shows no shame. Even when a complete stranger sees her naked she just smiles and talks normally, and even when Eric screws around with other girls she just acts a bit jealous but still participates in the group sex in the bathroom in the end without needing to be pushed into it. It's like the author is showing you that this is how Tiris was supposed to end up, in fact NTRPG was based on the idea of showing the fall the sweet and pure Tiris to a wanton slut who's banged every guy in town and is now completely happy with it and not bothered at all. We were supposed to see the whole process of her ending up like that, but the game stopped with it still incomplete even if she was already far along.
Also if you go to the village elder's house right after they arrive there, the elder will make Mars help Tiris carry her bags upstairs, during which she forms a temporary party with him. If you check her status there, you'll see a list of all her sexual partners, including most of the male characters who appeared in game one, plus her own father and even Leon himself. Which really makes me wish to have see how that would have gone down. Did she do it with dad just because she had gotten that slutty? Or because Eric/Libido suggested it and she did it to please them? Because the latter gives me more of an NTR feeling, just thinking that she had fallen to the point that she was willing to commit incest and seduce her own father just because one of those guys thought it would be interesting. Plus having the father in the game at all should have been a flag since no other parents seem to exist for Leon/Tiris/Libido and the fact that he was only there that one morning telling you she was probably at the shop.....I was slightly anticipating coming in one morning to find them banging. As for the Leon bit, that might have been just as interesting? Would it be similar to the scene with Mars and Filia in game 2? I wish we could have known.
Those last two scenes with Eric and Libido were good, but Tiris still had resistance and had to be fucked into submission by Libido before agreeing to the mixer and even had her drink spiked along with the other girls. And with Eric she was still very embarrassed being exhibited by Eric in front of the "staff member" until he did her up to the point she just gave up. Both those scenes should have recurred showing up until Tiris would finally agree to the mixer with a smile and go along with impromptu group sex when the time came without any need for chemical assistance, and would happily fellate and screw Eric without hesitation while the staff were there, even smiling and chatting while in the act.
For another thing, why include and wedding ring and church in the background if it wasn't leading to some big wedding based NTR moment (rather than some lame cop out dream of the wedding)? I'd been anticipating the finale of the game being a big climax where Tiris and Leon had a beautiful wedding before a smash cut to the reception where every man in town lined up for a turn with the bride while Leon just sits there as a bystander the only one not able to enjoy his bride on the wedding day. Anything similar to that would have been fine, the author just added that dream to justify the existence of those items after he decided to call it quits.
Most of all was the fact that the main reason Tiris didn't fall completely during the game was because she was still clinging to the fact that no matter what perverted things she did or how much a slave she was to those guy's dicks, it was okay because "Leon didn't know"! I was deeply anticipating the moment when Eric or Libido would finally unveil at the key moment that not only has he known all along, he's even watching right now! I was waiting for it so much that when it never came I felt quite betrayed. I was dying to see how she would react. Would she hate him? forgive him? Or at her most vulnerable moment would those guys convince her that it was alright because Leon 'likes to watch her' so she should just stop feeling bad and enjoy it. I think the last one is the most likely, but we'll never know.....
As for NTRPG2, well that's another long rant I can't be bothered writing right now. But looking at the flow of events it's obvious there was meant to be another phase. Phase 3 was Maria's phase and should have ended with the truth about her and Abel being revealed in front of Mars' eyes without any room for doubt. Then phase 4 would have started, probably with the manor being completed where the lumber field used to be where all the villagers had been building during phase 3 without explaining what it was going to be, and Ragnas moving in, with this phase being about Filia and Maria completing their fall and becoming happy sex slaves who'll do anything or anyone those guys ask them to. The stuff with Gerudo involving both Maria and Filia should have been the main focus when it was introduced and deserved a lot more build up, keeping your attention on Ragnas and Abel and letting you keep seeing Gerudo as the idiot panty thief for as long as possible before ambushing you from the side with that scene when Mars comes in to find Filia being screwed by a guy he can't see with her in the way and revealing it like that, and soon after revealing that it wasn't just Filia, he had also done it with Marie the day after Abel and Ragnas took her virginity. That really needed to be explained too, even though I can speculate on how it came about it still galls me not knowing for sure.
The fact is that he took stuff like that bit with Gerudo and Filia and shoved it all into one big climax including many of the ideas he had intended to introduce naturally as the game when on, but now wouldn't be able to.
The hints he threw in with the xmas one, with those still pictures confirming Marie with Gerudo on tues phase 3, don't make up for it at all.
