Whether based on real people, or classic boxing movie tropes, characters are an important aspect of any good "rise to the top" sports drama.
Fight Night: Champions is going to tap into your nostalgia for Rocky (and it's subsequent sequels) to give your boxer the dramatic journey he deserves. It's not like sports franchises haven't tried this route before, but Fight Night leans more on the cinematic than most. Which could be a good or bad thing depending on how you like your sports games. Check out the video to see if you want a little drama with your jab and hook.
