This is the best simulation-oriented boxing game ever made by a comfortable margin. That's not really saying much, since boxing is the rare sport that has never really been well-served in the world of games (outside of Punch-Out!!). The only complaint I really have about Champion is that its default roster was pretty weak, but luckily, its create-a-fighter mode helped with that. It has some niggling flaws - nearly every fight ends in a knockout - but I've played hundreds of hours of this game in the past, and I expect to play many more in the future. This is not because it's some sort of masterpiece, but because it's the best game in the space, and there isn't going to be a better one in the foreseeable future.
