Source is ending credits from people who already finished the game.
==SPOILERS WARNING==
fyi, since the credits for the PC port are now available: contrary to speculation that this was a sega europe project, it appears to have largely been developed in japan.
the director on the port was daisuke yajima from atlus, who was a programmer on p3/p4/p5/pq, and the art director was sachie tousuji, who did interface design for p4/p4g/pq/p5. most of the actual development work appears contracted out to preapp partners, which is a japanese dev house. all the programmers on the port apparently worked on the pc port of a hyperdimension neptunia game a few years back too, haha.
==SPOILERS WARNING==
Combined with the fact that they just setup their own developer page on Steam last week, is it the start of a new age for ATLUS?The credits are up on YouTube, but anyone new to the game may want to beware of some spoilers in the video as it includes some footage from the true ending route.
