I don't see why it's not possible to be honest, charismatic, and responsible while being a "player" as you put it. My only problem is that if you are one of those guys that has to trick women into sleeping with them by leading them on and giving them false promises just to get them in the sack, then you are making yourself less of a person and more of an animal, giving into your urges and lowering your vibration.
If you follow the very suave and very sophisticated gentlemen and how they interact they have a grounding of character which gives them their charismatic good looks and that's what gets them the women so often. They cherish and value the women they seduce, they make them feel like they are the most important and beautiful woman in the world, and then promise them a night of passion and adventure, all the while being straight forward and honest about their intentions. I think most women would agree with me when I say that it's the men that most make you feel valued and worthy that are attractive to you.
However, if all you want is the sex, and you're willing to lie and cheat to get it, then I would say avoid these personal development forums.
But if you are willing to improve your character and then work on how to value, cherish, and impress women, then I say go for it.
