Except with the PS3 nothing is truly Japan-Only. Just stuck behind a language barrier.
I'm still floored by Sega releasing a Project DIVA game here though, thought Miku was still too Niche for 'Murrika but I guess they might be trying to change that?
Not like I care about Miku but I wouldn't mind seeing more traditionally JP-Only games hit other countries. Though I guess I'd only really hope for SRW or ACE, and neither of those will come out if Macross is involved because Harmony Gold is a bunch of twats.
EDIT: Ugh, I feel like I'm starting to ramble or make Gaia-esque posts again.
