And harem games with a giga-alpha like this one are enjoyed by those guys that never see a pussy but are happy to fap to what they think they deserve.
Interesting theory but completely wrong. First, not all people only phantasize about stuff they cannot get, some also do stuff they can do but in a different version. Like NFL players playing themselves in Madden. Then you can have a fulfilled sex life but still dream of stuff you wouldn't want in real life - an RL harem would be a nightmare to me, especially as it is depicted in these games, still it is a fantasy just like I do not want to do stuff in other games IRL even though I maybe could, like car racing.
Not as important, but just an addendum: not everybody playing these games faps to them.
All the alpha, incel and MGTOW stuff exist because many men see no pussy in their entire life. Pretending the alpha status has nothing to do with how much pussy you get is delusional.
For some social circles this may be the case, but in others it certainly isn't. You may have "alphas" relying on the biggest car, the most money, yes, also the most sexually active, but as said, this is not true everywhere. Many people's evaluation of others does not rely on the number of their sexual conquests and in most circles you don't talk about it to begin with.
However, the common definition of the term (when ascribed to males) is that of behavior: reckless, trying to be dominant, not caring about others in their group and their sexual partners, more stuff like that.
However, I will not convince you, you will certainly not convince me, so I will quit this discussion.
