From the review, "If you take away anything from this review, let it be that Pump It Up: Exceed Portable and Pump It Up: Zero Portable are pretty much interchangeable. If you own Zero Portable, you don't need Exceed Portable. These two PSP titles aren't like DDR entries, where there'll be different songs, patterns or mechanics. Instead, Zero Portable is more like Exceed Portable 2.0 rather than a whole new game.
This means that almost everything I said in last week's Exceed Portable review carries over to this week. Sure, there are a few differences, and those differences are what this review will focus on. This review will essentially help you decide which Pump It Up Portable would be best for you."
