You can still have an evolving story happen and it’s not about the player building that story. But the story results from the choices they make in the situation you present.
Be a fan of the characters. Be on their side. Focus your prep around them. Help them look awesome. Avoid “gotchas” that characters would have picked up on but players missed.
My own groups are trying out the luck system from Tales of the Valiant and like it so far. It's extra bookkeeping but has some fun options and makes a series of bad rolls work out much better. As a GM, I like it a lot because I don't have to keep track of it at all. It's all player-managed.
Close! It’s my wife and I now 😀
