Leading someone on generally refers to telling someone you like them, love them, whatever, when you really don't. Whether that's to get something sexual, or just some attention is different for different guys.
Playing games generally refers to not coming straight out and being 100% with what you want, maybe saying you like them one day, then not another, then back to liking them later. It's like he was straight up with what he wanted, and didn't try and "have fun" with trying to get your interest.
Not sure how accurate it is, just my opinion from someone who hasn't done either playing games or leading someone on.

Real men and women, don't play games. My boyfriend didn't play games w/me either. People who play games aren't interested, just want sex or want an ego boost.
