Dunking, blocking shots, and the overall arcade feel make this fun to play, the gamebreaker on the other hand...
The dunks in this version of NBA street is the best feature. It is rather fun to do a double dunk or jump off someone's back. Alley-oops are what I remember them being and it's a good thing that wasn't changed. Basic dunks are still around and look almost the same in the previous games as well. The basics are still there and that's what you need in a good sports game.
Blocking shots are as easy as I can remember. That isn't always a good thing as this may not bring about as much of a challenge from the CPU or other players. What I have found other people doing is clearing the laneway with fake alley oops for the CPU to jump and take both of you out so that someone else can take the 2 or 3 point shot in order to run away with the game. This can be very aggravating at times. You are more likely to see this from a human player that doesn't know how to play.
Someone mentioned in a previous review that stealing is too easy. Well, on easier difficulties it is for everyone. Some people on the more difficult levels of play have to time the steals perfectly. When the CPU has a gamebreaker, good luck at trying to steal. 90% of the time they execute their gamebreaker with at least +3. At least winning isn't too easy to come by.
Now why was the gamebreaker bad this time around? Simple: when the gamebreaker is activated by anyone, the player with possession of the ball starts to break dance when you hit the trick button. Modifiers just make it more ludicrous. The other team steals the ball or gets possession, they get the gamebreaker and your metre empties. In previous entries as well, the gamebreaker seemed much more fun to pull off. In this one, the gamebreaker doesn't have any realy special dunks or shots to pull off like in Vol 2 or Vol 3; it pretty much only has what you can do without the gamebreaker.
This is more or less a rental first. Previous NBA street titles tend to fade into obscurity in about 4-6 months. Expect this one to be the same as it does not improve too much on the previous entries.
