As for my case , I don't mind controlling the MC . I've said this before on another thread but I'll say it again here. It adds this extra layer of spice when I get to control and decide what the outcome for the oblivious MC. It's my sadistic nature kicking in basically. Then again , that's just my take on it.
Edit: Also, one of the reasons why I dont like netorase is , the idea that the one getting cucked is getting PLEASURE from it. I want to rob that pleasure away from him as well, hence I just prefer netorare and netori.
Also , this game has other aspects besides ntr , since the mc can fuck npcs that you find attractive. It also has a pure love route, if I remember correctly.
You could, but sex content for MC is VERY undercooked, to the point that less would be lost scraping MC content and shifting focus purely to the priestess than scraping Netorase content. I'm not even sure I could understand it from a sadist's point of view, given you won't get the actual payoff for years (maybe), and until then, it's just standard cheating.
It's actually rather a shame that the best NTR in the game is a flashback scene of a girl the MC wasn't even dating. And of course, that scene was devalued by the lord just having magic demon fuck powers, which puts him on the same level of loser as the MC that needs a magic curse ring to get ONE girl to notice them.
If the point is being sadistic, I don't see how behind the back cheating really does that. It's why I see more potential with Netorase events that CAN spiral down to outright NTR rather than just behind the back cheating that MIGHT get payoff in a couple of years.
I think Netorase events provide an excuse for Priestess to be psycho about MC while having sex scenes with others (I'll tell you, it's very weird MC can get gutted found having sex with PM with she's a total Yaziro addict and at that point only stays with MC because Yaziro told her to). And allow for more flexibility in terms of handling. Netorase can very easily spiral into NTR if handled incorrectly (forcing Priestess into fucking people she doesn't want to, handling the aftermath poorly, etc), and since we can't get a conclusion to outright NTR until the game's finished, it's the next best thing to actual NTR rather than just behind the back cheating.
