that's a tough question, i would be scared of getting my feelings hurt! how about casually date the person and have fun (not sexually lol) until you see who they really are and if they respect you as a person. how old is this person and how do you know they are a player?
Being the very cautious person I am, I use the past as an indicator of the future. I do believe people can change, but chances are no. Although you could play hard to get and see just how hard he wants to date you, but that opens up another can of worms.
Yes I sure would date a player. I would date him just to show him that any game he runs on me - I could run one on him better. I would avoid falling in love with him and keep him at a distance but I would be the one to let him know that I got more game than him.
