In the OP you are referring to situations which is basically a group of long term friends with little or no new people coming in or going out. These groups tend to be too narrow and stable to be able to attract women.
What you need is a social group that has a core group and other men and women coming and going. So I dunno maybe a bunch of guys regularly hit up a bar or some other places where the people there are also regulars. Then over a few occasions you 'befriend' some of the women and run game on them. Obviously its up to you where you wanna take it from there if you want a casual thing or ltr.
Obviously most guys are not gonna be able to bang hot women regularly. Its just a question of what level you are in the game. At the moment more low-quality men are getting sex from women because there is no real value out there to pull that stuff away from ONS. But the game will likely develop in the future and then I expect slim pickings from cold-approach, nightgame or whatever simply because women will actually know which type of guy is the best guy that brings the most value and by comparion some guy cold-approaching for a date or to get laid will be seen as low-value.
Social groups are gonna be where the developments the game are likely to come in the future. Women are looking to be part of groups that include men and especially other women moreso for younger girls. A guy who can network girls with other girls and provide them with the life experience they want that they cannot get elsewhere is gonna be able to trump every other type of guy.
Game has many more levels than just "be aggressive, open, stupid boring convo, number, date etc" infact I think all of this is gonna be irrelevant in the future as it is mostly going to be all some form of social circle game.
