Hatsune Miku: Project Diva Extend

[LunaMoo]

May I ask? Is this a sequel to the original one or juz some add-on to the original one? ._.

(the original one= Hatsune Miku: Project Diva)

Extend is an extenshion, but not of the first game, rather of Project Diva 2nd, it has some different songs(it has some, but not all from 2nd), and more character modules, but overall it's same game, best value of the three psp PD games when it comes to amount of content, althrough it should probably depend more on the songs you might like.
