I'm accustomed too. The puck collision seems a little wacky at times. Sometimes you'll shoot a puck that appears to be in your skates. The trade system allows you to trade any jerk for the best players in the NHL, which may please the people who want to unload that rookie for Jagr, but that's not at all realistic. The players in NHL 2K look great, except that some of them have pretty weird bodies.
Some guys look like their jerseys got stuffed with frozen ham, somehow.
There's only three gameplay modes, season, playoff, and exhibition. Worse, there's no practice mode or any way to adjust the number of games in a season. Maybe these would be adequate if the game was more fun to play, but it's not. The speed probably has a lot to do with it. The game isn't particularly slow or choppy, but the action is rather slow paced.
