Think we have a misunderstanding my friend.
When I say the "GF will cuck the BF" it's not meant as a derogatory insult, it's like saying the sky is blue, because it is. IMO if you enjoy these types of games, which I do, its eventual outcome will be largely tilted in that particular direction. If you say I'm a cuck for playing these types of games, well that could be true (maybe cuck-curious?). I play harem-themed too, with the same expectations, to either get all the girls or lose them. Although I'm not sure there is a stereotypical label associated with that type of psychology, Alpha maybe? IDK

moreover, don't care as it doesn't diminish my entertainment derived from playing them. I'm looking forward to playing his next game, and think you are too!
