I can understand that. Especially popular guys, who draw women to them like magnets, are nearly as hard to get a hold on to as HBs, since they have tons of friends and already hang out in larger groups.
Like mentioned above, how about you try finding someone suitable who has one or two interests like you. Then, if his social circle is suiting you (check pictures or ask what they always do), casually ask whether you could join them or make him offer it to you somehow (You are the PUA in the end
Usually, guys will be flattered and will probably agree, if he likes you. It's funny because gaming women compared to men is like professional football compared to elementary school football. They've never experienced people hitting on them for a selfish reason, they will see it as compliments
But beware of female groups. In my experience there tends to be a lot of jealousy and hate when confronted with a talented PUA. That group will fall apart and you will just have a few lays instead of getting a great new social circle
Try hanging out with multiple guys with couples included where dating the females is off limit
