I wanted everyone to be able to play the game on a large high-definition screen. Honestly, my eyesight’s getting worse, so it’s getting difficult to see things on a smaller screen. I’ve seen some questions about why Type-0 isn’t being released on the Vita while X/X-2 HD saw a Vita release. The reason is that the X/X-2 HD Remaster was developed on a PS3/Xbox 360 environment, while Type-0 HD was developed on a PS4/Xbox One environment. So there is a great difference in the technical specs and it would not be easy to export the data to the Vita. As for a sequel, I would love to work on one if Type-0 HD does well.

Well... There you have it guys. Blame his eyes, and the PS4/Xbone.

I think it was right move. It looks great on consoles.

Lawl! They couldn't even just port the psp version and just translate the text because of his eye sight? Okay there SE

Although, since it is SE, it is kind of expected... I blame Sony cause they should have paid SE some extra money in order to port the PSP version to the Vita + translate it in english so they can show some better support for their handheld

Ha stupid excuse. PSvita 'environment' is closer to PS4 than PS3.
If it ran on PSP - vita could be an easy port

Well, I'm glad for that "PS4/XboxOne" enviroment thing. Not to sound like a douche to the Vita, but I'd rather have their RPGs developed/ported to home consoles rather than to the portable.

Coming from the company that ported the mobile version of FFIV to PC when ds version was better and an option, I just can't take them seriously. FFIV, the DS quality game, is looked to 15fps on PC. It's sad how lazy of a port that is.

They have a perfectly fine PSP version that you can enhance for the Vita. "We doubt it will sell much on Vita" would have been a reasonable answer.

I don't think they have any moral obligation to put it on Vita, but at least be honest. We didn't think we'd make enough money. Simple.

hmm, still would have preferred it on the vita. I prob wont buy this on XBO/PS4 but i would have prob bought it if it came to Vita.

On a side note. How is the FFX story? Like is it really good? Thinking about getting it and maybe it will be the first FF game i actually like

i don't know why they just don't say the vita is dead and its not worth their effort, (Why it wasn't ported to PSP in the first place because PSP was essentially dead at the time).

I feel bad for the Vita
