Summary: I bought both NHL Hitz 2002 and 2003. NHL Hitz 2003 is in my opinion the best game I've ever played on Xbox. I love the fantasy heads, fantasy rinks, and over-the-top action. I bought NHL Hitz pro hoping that it would be like NHL Hitz 2003, but improved (5 on 5 play, etc). It has dropped all of the fantasy elements that made the originals fun, there are no mini-games, the stats and customization features aren't as good, etc, etc.
Summary: This game proves that you'd better read up on your games before buying, and consider who you're buying for. I bought this game for a younger teen, as with the last version, and what a shock the changes were (I ended up having to buy him Tony Hawk's Underground shortly thereafter to make up for his disappointment in Pro).
