Well, I have the PSP version of zero no kiseki and I stopped playing it right after I heard the news on the Vita remake version. (I was playing sora the 3rd concurrently)
Not only this will have voice on events, it will definitely be in much better resolution.. Prolly the same as the chinese PC HD version. High frame rates, better animations and voice over! How can I play the psp version now?!
If they allow you to reuse the old saves I wouldn't mind doing my final game run for the series on Vita. :x I only really lack that nightmare run to complete my achievements... >.> --- Playing: 7th Dragon 2020 Anticipating: Nayuta no Kiseki
