Despite being absolutely insane the Danganronpa series has managed to settle in quite nicely among the PC crowd, so much so that the original now stands at a 97% approval on Steam - not the easiest of feats to accomplish. Given the reception so far it really shouldn't surprise you to hear there are even more Danganronpa games heading over to the PC in the near future.
This time around its Danganronpa Another Episode: Ultra Despair Girls, and even though the name might lead you to believe its the same brand of madness, in reality it is more of a spin-off game. Unlike the visual novel style of gameplay from the previous games, Ultra Despair Girls is more of a third-person action adventure with horror elements. Perhaps it would be for the best if you just saw the trailer, rather than watch me desperately try to explain the unexplainable:
Ultra Despair Girls has been available on the PS Vita for about a year now, and while I've never played it myself I did check out some of the reviews. Long story short, its has received a mostly positive reception, though there are numerous gameplay quirks that keep it from being as bizarrely enjoyable as the main series. Whether the PC/PS4 port will correct these issues and improve upon the gameplay, I don't know, but with the release set for Q2 2017 we'll have plenty of time to find out.
If you're interested in a few more tidbits of information, or if you're just wondering whether your PC will even be able to run it, I would recommend you head over to Steam. Just don't expect to find out what exactly the PC version will bring with it as that information has not been announced just yet. Once it is, I'll make sure to update you as I'm rather interested myself.
