They did a similar thing regarding a "one size fits all" story line in Don King's Prizefighter. I think you had around 40-50 fights, and it played out as a tv documentary about your fighter's career. It was fun the first time, but really limited the route you could take as you had to follow exactly the same career path every time. This could be a great idea if they create various routes that your fighter can go down, but it'll be very limited if you don't get that option
