That's okay. Games aren't made by a single person. I'm sure it will still turn out well.
No but the top like 5 people are responsible for acceptance for work, and basically the vision of the game.
you could have all the talent in the world but if you don't have someone who can't take that talent, smash it together with a clear vision and do it in a timely manner your project will stumble
FFXIV is the greatest example of that.
