An NTR multi-route game having a route where the MC gets revenge is fine.
But as a single route game, I don't think it would be appealing. The point of an NTR game is the MC getting screwed over. If I don't want the MC to get screwed over, then it makes sense to just play a non-NTR game.
Can you explain why you'd like an NTR revenge game?
Because there's plenty of games where the MC gets screwed over with zero chance of revenge or redemption. If there is it usually only exists so he can get screwed over even harder.
And in the few stories where there's a 'happy' ending, the slut usually goes back to him because he provides stability, not because she changed her mind or her crotch.
I mean, there's even a real life example--look at George Remus: a Prohibition lawyer who made it big, got caught, his wife ran off with the agent who investigated him and sold everything except his house. He broke down in tears when he got out of prison and returned to a home that was literally emptied. Cucked and Screwed Double Whammy.
He later ran into his wife and the agent, got on a taxi and had the driver run them off the road, where he got off and shot them both dead. Then he immediately turned himself in.
The jury found him not guilty. THAT, combined with other good revenge stories is what I'd like to see.
