"NHL 97 took the graphics even further ahead, using a full 3D engine, with motion captured polygonal players (PlayStation/Saturn versions only, the Mega Drive and SNES versions retained similar graphical values to previous games, but with further enhanced animations). Each goaltender has his own custom-painted mask and the original artwork can be seen inside the game with a special "Goalie Mask Viewer". NHL 97 also introduces play-by-play commentary, provided by well-known announcer Jim Hughson."
