Anarchy Reigns was sent to die as Sega was busy canceling Bayonetta 2 and Virtua Fighter has largely been a dead series.I dunno why people are expecting PC ports for everything.
Yakuza and Project Diva aren't the only series which haven't gotten PC ports recently. Anarchy Reigns, Viruta Fighter, Puyo Puyo, haven't gotten PC offerings.
Puyo Pop Fever did actually come out on PC in Japan.
I mean even NIGHTS and Jet Set got a PC rerelease.
