It's always good to have a primary source. She can probably also give you ideas about plots and storylines that we mere mortals can't even think of
.
Do what you find interesting. Don't get over ambitious, that can kill a game, don't include too many characters, this usually just makes everything worse, but then tell the story you want to tell.
That said "Being the best in the world" is not a good goal, because it's wishy-washy. Instead, "winning this (inter)national competition" is a good goal, and it also aligns with many classic stories of a group of nobodies who join together, train, improve and have setbacks and surprisingly win the big tournament. Of course, this game should be a bit different, because, and I assume I speak for many players, I want to see sex, intrigues, power dynamics and more that can't be shown in your family friendly underdog movie.
