XSeed is just as much to blame as VW
No, they're really not. They actually had the game translated. It was done. Vanillaware completely dropped the ball on this one.
Yeah, Xseed made it very clear what happened, and in almost all cases it depends on the developer to get the localization put in, not the publisher, so don't go blaming them for this. Even if you try to argue that they should've known Vanillaware couldn't handle it that's ALSO VW's responsibility as they should've evaluated if they had the man power or not before finalizing the deal.
There is no way this is XSeed's fault. XSeed is fucking awesome and brings people games that they would NEVER get otherwise, but they can't do it all on their own.
Also, I'd really like to play Grand Knights History. Give these fancy grajamate school Japanese skills a whirl in real time. Maybe I should pick it up.
