It may be time to move on to the next generation with Project Diva X for Playstation Vita and Playstation 4 where we may expect some new graphics that challenge the potential of the Playstation 4. In the present time, the Playstation Vita version was already out but the problem against buying it is that the game has story mode in addition to Free Play mode. Not to mention that the main menu takes place in the Diva Room and you’ll be requested for some stuffs for real as if the Diva Room is getting more improved even more in terms of behavior. Other flaws people know of are that the songs in Story Mode are played in lower difficulties and you need to unlock those songs through that mode.
Perhaps, I’m waiting for the English version to be out for full understanding of the Story Mode if I want to get through in the future.
