For those that need a fix, I highly recommend a similar rail shooter of equal quality such as Sin and Punishment: Star Successor. Be careful as this game is tough. Super tough. Developed by treasure. The same team behind Gunstar Heroes, Guardian Heroes, Radiant Silvergun, and Ikaruga. I hope you kept your Wii or Wii U console. Wiimote and Nunchuck are the best way to play this game, but his versatile control options. You can even used Gamecube controllers.
There is also Asura's Wrath. It's more of a gameplay roulette, but has rail shooter sections that play similar to Panzer Dragoon. If you have an XBONE or Series X, the game and all of its DLC is backwards compatible.
