Worthplaying has posted their review of NBA Street Showdown, giving it a score of 6.8 out of 10.
"The final verdict is: fifty bucks? No. Okay game? Yes. Hopefully, when the inevitable sequel to Showdown releases, we will have a spruced up release to compliment the new mechanics and overall sensibilities of the latest NBA Street game along with it. The PSP is far too powerful to be a dumping ground for cheapened cash-ins."
