Genuine question but why are people into NTR? Like what is so good having someone stolen from you? I can get it if you're the one doing it but you're not.
Honestly, I couldn't care less about the NTR aspect of many NTR games, and often find the NTR almost getting in the way. Particularly in Netorare games (think that's right iirc. Netorare was like girl getting stolen from you, Netorase was you actively engaging in a cuckoldry fetish, and Netori is you stealing someone else's girl?) Notably tropes like "MC is a total pushover" "MC has hyper-puritan values" "MC has a micropenis" "MC is totally/willfully clueless" particularly are annoying, as it tends to push the "you have no control over the situation" which is just, not a terribly fun game, imo.
Of course, part of that is because the corruption side of NTR tends to be much better, while also not going as exteme into total bimbofication of the FMC as more straight corruption games do. (Give me the prim and proper office lady exterior who just cannot wait to break that facade and indulge in her lustful impulses. The cool, independent tomboy that is excited to kneel to blow you at any moment. But don't completely strip away their original personalities in the process of corruption. I'd love to see more corruption games where the corruption becomes a new, hidden side of the character. Subtle changes to everyday appearances, maybe more obvious changes to behavior. But not a total makeover.) NTR games often end with total slut-ification of FMC's character, but it does tend to be a bit more gradual and require a bit more "maintaining appearances" on FMC's part. Additionally, hidden sex/exhibitionism scenes are one of my personal favorites to see, and NTR is one of the most consistent genres to include those.
Personally, I'd love to see an NTR game where it's totally possible for the MC to keep the girl AND MC turns her into a complete nympho. Instead of the usual "you get maybe a token, stale vanilla sex scene for keeping your girl until the end", your choices determine if you stick to the usual "puritan MC wimp who keeps the girl in a very mild relationship", your girl gets totally corrupted by others, or you chose to fight for her, maybe even become the very douche-chad MC rejected in the process, but both keep and corrupt FMC yourself in the end. But that's probably not really what the average NTR fan would like. So I doubt I'd see much of anything like that. (I think there's a guy who's slowly working on a game that might have something similar as an option, but been a while since I've seen an update on it.)
