To me the "game" has always been and will be about a persons confidence. I don't care how you look or what shape you are in if you have confidence, not cockiness, you have game.
My theory, and I don't think it's gender specific, is if a person is truly "comfortable in their own skin" they can be very attractive to others. Like you, when I was younger I was in shape, lived life to it's fullest, but I was incredibly cocky! My "game" back then, I think, turned a lot of women off. In fact when I first met my wife she absolutely hated me because I was so cocky, I know this because she let me know that more than once. I guess I wore her down and she agreed to go out with me. After some self discovery and reflection I was able to become totally emotionally available and vulnerable with her which took our relationship to an entirely different level, leading to marriage. Although our relationship was short, 2 years with only 6 months of that being married, unfortunately lost her in a car accident, what I learned about myself and relationships was a game changer. Don't get me wrong, I can and still do disappoint women on so many different levels, I'm a guy after all, but I try not to be "that guy...."
What I'm saying is that you just need to be you! Let people in, be a little vulnerable. No matter what you look like, no matter what shape you're in, if you are a good person and people can clearly see that your will have "game."
Hope this helps my friend! Please let us know how it goes with her......
Best of luck & be safe!!!!
