This.
Edit: I'm playing this game since the first one with my US PSN account and I don't have any problem at all.
no its not just that but there will befree missions and other things lined up which i imagine will be pushed through the connecting with gundam perfect games server as there is a disclaimer that boots up every time.
Whats the extra content? Im really lost here. Ive never imported a game. Hell I dont even know how Im gonna get past the language barrier. This seems like a fuckton of hoops to jump through to play this game... I dont have a JPN account and would rather not have to make one and wipe my vita etc...
First off reason why Im telling you this is, I prefer fellow GAF users to know exactly what they are getting into when importing a game. Which also includes what you might miss out on by not having a JPSN account. Therefore from there its up to you to decide if you really want to import or not.
Basically extra content is usually locked via PSN regions. So in this case JP version of Gundam Breaker 2, you need a JPSN account to access standard DLC for it. Reason for this is Age Ratings and certification for said region. Which is why DLC is not region free.
Updates are handled differently and do not require the same region PSN account to download. That is why even if you have a US account you can still get updates to JP titles. There are occasions where extra content is pushed out through these updates, but it is not always the case.
With that being said it is why I am trying to let you know that you might be missing out on future content. At this time since there is no extra content yet, we do not know how it will be pushed out. Either by updates or via JPSN. Though right now seeing some of the system messages that pop up. I have a pretty strong feeling that a JPSN account will be necessary if you do want to partake in said content.
This game does have more than enough standalone content to be worth the price though. But at the same time just know that if there is extra content via JPSN you will miss out on that by not having a JPSN account.
In Short
DLC = Same PSN account as region of the purchased title.
Updates = Any PSN account
---
Am not saying you need to reformat your Vita, but just know what you could be missing out on.
Its not really jumping through hoops as the title was not made for other regions. And it has always been this way with the PSP / Vita with content. Or should I say importing titles since the PS3 / PSP generation which use PSN.
Next issue is language you seem to be worried about, we have lots of members here who do not know a lot of Japanese yet play the games just fine.
Anyways if you have any more questions feel free to ask!
