NHL 98 features much faster and refined gameplay, now using four action keys instead of two, removing the need to double-tap to perform some actions. Other new features include "in-the-fly" tactics developed by Marc Crawford, manager of the Colorado Avalanche, and new commentary lines from Jim Hughson and Darryl Reaugh. The game's graphics are improved compared to its predecessor, with players appearing less angular and textures showing fewer pixels thanks to 3Dfx support. In-game presentation follows a TV-style script, zooming in on players while displaying stats during clock stoppages.
Game modes include the Season, where you can choose between playing 25 or 82 games, and the Playoff mode, which allows you to play best of 1, 3, 5, or 7 matches. The game also features an international competition with 18 teams from around the world, reflecting the first Olympic Tournament with professional players.
