I dislike the term 'pick up artist' because it limits the usefulness of the science. Not every man wants a series of one night stands quite apart from the dangers involved. Condoms split and I cannot see why they should be 100% effective even if they do not as the woman's juices will still come in contact with the base of the penis even with a condom.
I am a romantic and want to find that one special woman. I suspect that many other men are as well but we feel that this is somehow un-masculine to admit this.
Game can be used for monogamy or simply to obtain respect from women at work. This is why I prefer the term 'gamester'. It implys both gangsterism and fun which seems appropriate.
