I give it a 10. Not because it's impossible (like holding all belts online at once in Fight Night), but just for the amount of time and prep it would take to get a platinum. It makes other time consuming games look easy.
Battle trophies are so incredibly random with things like "hit for x amount of damage".
Good luck to anyone who can put up with the game for the hundreds of hours it would take to get the platinum.
