It would be very interesting if a trend of developers implementing what I call "NTR tension" were to spread.
This would be especially useful in games with a fantasy or post-apocalyptic context, where the protagonist, in a hyper-competitive, "grimdark"-type setting, has to fight other equally strong and intelligent male characters. It would be like a sword of Damocles (in this case, a bull's sword) hanging over the player's head.
This would help to create interesting differences in game development; this way, NTR would be an aspect of the narrative and not just a bad ending.
I tried to suggest this once on the Desert Stalker forum... I almost got lynched by the cyber equivalent of the Puritan Inquisition.
Sad but true... but I still have hope.
