The graphics are nice but the boxing mechanics are awful. Many punches in a combo aren't recognized by the game, uppercuts barely register or work even though the opening is there. The game has you in orthodox even if you're a southpaw. The dodging is sketchy. Pretty much if you've ever sparred or fought you'll want to tear your hair out.
On the plus side the graphics are great and it pretty fun to be in a VR ring fighting. If you want realism look elsewhere but if you want to just ignore reality and work the game's mechanics it's ok.
