I do not usually write game reviews but being a boxing fan, I found this to have good replay value for me as an older gamer. I have only played singe fights and a career mode, without online play.FightersThere are a decent number of professional boxers in the game to include Muhammed Ali, Sugar Ray Leonard, Tyson Fury and Oleksandr Usyk. Missing are people like Mike Tyson, Evander Hollyfield, Lennox Louis, Marvin Hagler, and other big name notables.The interface of the gameplay is versatile, as it can use the buttons or the Right and Left Joystick. What I liked about knockdowns is balancing the power bars rather than the hurried pressing of a button to recover from a knockdown.Response of the game to the controller is good.Graphics are decent but could be better in terms of shading and lighting of the characters and the ring. Boxers get swelling or cuts, though, when a boxer is knocked down, the extent of injuries are not necessarily reflected. Animations are good.One bug I noticed is when the clock runs out, I have been able to resist a knockout and the game endlessly stays at 0:00 allowing an all out brawl without officiating. You have to restart the system to get out of the bug.Progression for the career allows the user to choose resting, boxing training or social events. That beats having to do mini-games to better a fighter. As the career progresses, the boxer can work towards rankings, money, fame or build their boxing record. You have to select various staff (coaches, cut person, manager) along the way, as you progress. The coach can be upgraded as each match is won to improve boxer's attributes. You may select 3, 5 or 7 match resigning of staff. There is no interaction with staff in the game, per se, apart from choosing one versus the other.Once a title match is fought, it is automatically set up for a rematch; though I wish a rematch option could be deferred if the championship belt holder doesn't lose. Once the fighter wins the Unified Championship, he or she may continue the career defending the belt or fighting other boxers.There are two upgrades to include other boxers with downloads. I got both when they were on sale. They add to the replay value of the game, in my opinion. Overall, I am pleased with the game though the graphics aren't up to the usual PS5 level.
