I've studied Janka's stuff and definitely think there's truth in his words. He seems to have learnt the game by cutting his teeth in the field. True he does have movie star good looks, and surely that's a major pull but that can only get you perhaps 10-20% extra women and could also improve the quality you are getting. Ultimately you do have to have solid game in order to convert the attracted ones into lays and to rake in numbers. I can say this from experience - when I was a noob I lost chicks that I had made out with/gotten BJ's from, all coz of not having tight game.
Game is a necessary evil
