Hockey is a game of coaching an NHL team, including drafting college players, trading, selecting and cutting players, choosing overall game strategies, and realistic playoff selections and the Stanley Cup. It is possible to let the game run all by itself, but that’s not really much fun. I only use it for beginning a new set of teams, so that the NHL is up to a decent level of competition when I become the coach of a team. As a coach, you can coach any NHL team, and have an equal chance of succeeding with any team. The computer can play at three levels, ranging from rather easy to quite difficult (for me, at least).
Some features of the game are the accuracy of the coaching job, letting players get older, which gets them better at first, but then they go over the hill, and the excitement/heartbreak of seeing your team win or lose because you decided to try a different offense in the playoffs. Teams are a full 45 players, and must have reserve players in case of injuries.
