Game exists. It's called social acuity and ability to convert "maybe" girls to "yes" girls. Anything else is determined by looks, money and status.
Chances are he only wants to **** Stacies. Stacies go for rich guys.
There is really no such thing as game, man.
When you meet a woman if she has no interest NOTHING you do is going to change that, no sense even trying.
When you meet a woman that has some interest it could be on a spectrum of very high interest to luke warm interest. You are better off going for women that have high interest, everything lines up and progresses naturally without any real effort. Do you think if a woman was truly interested something like double texting or this other b.s game "theory" is going to ruin your chances? lol
The problem is that the vast majority of men's experiences are with women that are luke warm at best. This is why men start reading all this PUA nonsense and talk about this bull **** about game, when it's really them just failing to recognize that these women just aren't all that interested to begin with.
This has nothing to do with "game", again it doesn't exist, and more to do with the reality of the current dating market. Women's expectations of men are much higher than they were before the advent of social media, dating apps, etc. They could then even meet men that meet their basic criteria but then reject him for something else. Think of it this way, a man meets her basic checklist but then she begins to filter out for personal compatibility. This could literally be something like her not liking his sense of humor or maybe he has some sort of quirk or mannerism that she finds annoying. It could be something like the tone of his voice or laugh reminds her of some ex or some **** lol. Nothing here is about game and just personal compatibility and just overall femal pickiness today.
A woman today could EASILY talk to more men in one year than a woman 30 years ago would have in an entire lifetime. The result of this is the women are much pickier and more selective with their potential suitors. Think of it this way, if you had 100 women messaging you right now would you have the time to go out with all of them on a date and actually get to know them. The answer is no, so you'd become more selective with what you choose. However, because you are aware of this abundance you are far more readily willing to go to the next and the next, etc. In contrast to this, if your options were far more limited you wouldn't be as selective.
Everything I'm saying here is common sense. You and other men would be far better off just accepting that these women aren't all that interested.
