The amount of game a man needs to sleep with attractive women is inversely proportional to his looks.
I remember trying to game women after a lengthy period of almost hermit-like self improvement. Regular gym sessions, clothes shopping, new haircut, better grooming, etc. The first time I asked a girl backed to my place and she accepted I thought "Interesting". Then when I got to my bedroom and the clothes were off I passed it off as a lucky fluke. In the not too distant future I brought another girl back to my place and when I told her we should "take things upstairs" she complied. "Is it really this easy???", I thought to myself.
Yes. Yes it is.
Men should be investing energy in improving their looks if they want to do well in this game.
