Update: NIS America has offered up a statement about the rating.
"We submitted the ESRB rating for a PC version for the possibility of releasing Disgaea 5 on PC at a later date. Currently, there is no timeline as to which Disgaea title will be headed to PC," said an NIS America spokesperson.
It seems that the Entertainment Software Rating Board (ESRB), the independent group that rates nearly every game that comes out in the United States, has rated Disgaea 5 Complete for Windows PC in addition to Nintendo Switch. This could be pointing to a Steam release of the title, though NIS America has yet to confirm anything officially. We've reached out to the publisher for comment and will update when that comes in.
Nippon Ichi has found success with releases of its games on Steam, following comments in 2013 by NIS America president Haru Akenaga.
"For PC, we are going to release several titles for Steam. I can't say for sure, but in the future there may be a chance [to see other] Nippon Ichi titles on Steam. We are planning to do something seriously with Steam," Akenaga said at the time.
When it comes to the Disgaea series, NIS America has only released Disgaea, Disgaea 2, and the Disgaea-ish Phantom Brave on Steam. Given those previous releases, the expectation was the next port would be Disgaea 3, but if this is true, Nippon Ichi is jumping all the way to the latest game in the series. Could we see a simultaneous release of Disgaea 6 on PlayStation 4, Nintendo Switch, and PC in the future?
It is worth noting that while Disgaea and Disgaea 2 were released on Steam, neither game was reclassified with a PC release on the ESRB website. It seems they simply carried forward their Teen ratings from earlier versions.
