Horrible...Not even a big-name license such as HBO or a high-profile cover boy such as George Foreman could save this boxing debacle, thanks to its awful graphics, horrible control, and crappy gameplay.
The game has the worst combination of problems a boxing game could possibly have: sloppy controls, horrid animation, and poor collision detection. These detrimental factors ultimately make HBO boxing a bigger waste of money than the Tyson vs. Golata fight.
It's a real disappointment, it's not fun, and it looks bad. It's not even a potential contender, and if Apollo Creed or Mr. T. ever got ahold of this they'd eat it for breakfast, and they aren't even real boxers.
