Warriors games--or Musou, depending on your preferred terminology--are still going strong, so why not reintroduce the one that started it all? Dynasty Warriors 2 wasn't just a PS2 launch title; it forged a new series (perhaps even genre?) featuring 3D crowd combat, hack n' slash combat and capturing bases. Don't be fooled by the "2" numbering: the original Dynasty Warriors was a simple one-on-one fighter.
Dynasty Warriors 2 was released on PS3's PSN back in 2012...but only in Japan. Perhaps that renders a Western rerelease all the more unlikely, but that it launched a popular franchise (which inspired spin-offs based off Zelda, Gundam, Dragon Quest and One Piece) means it deserves an HD uplifting.
