But, that's the thing. They *can* get it. If you own a PSP, you can play Brandish: The Dark Revenant. Whether or not you can do so without a PC, PS3 or PS4 to transfer it from is irrelevant -- you can't play it without wireless internet even if you do have to access the store directly from a PSP, so it's not like the PSP exists in a vacuum. The system is absolutely dependent on other devices in order to receive digital games, and I don't think there's a soul out there who owns a PSP and has wireless internet access but *doesn't* own at least a PC as well.
And personally, I prefer playing this game on PSP to playing it on Vita (if only because I can use TV-out from my PSP, which I think looks crisper than playing the game via PSTV as well), so if I were a European with a PSP and couldn't use it to play Brandish: The Dark Revenant because the publisher decided it should be a Vita-only title, I'd be *pissed*.
As others have noted, we're a localization studio only. We have no in-house programmers, relying on Sara for PC games and the original developers (or, in the case of Rune Factory 4 EU, a third-party programming house) for all console and handheld coding support.
