Trivia
     -See the mysterious wreckage in Georgius?  That's Shelcoof, the ancient airship you chase through Panzer Dragoon Zwei.
     -Where PD Zwei takes place:  Opening:Village of Cainus.  Desert Level: The Garil Desert.  Forest Level: The Forest of Zoah, of course.  You get to fight the worm-creatures in Path 1.  Tunnel Level:  The Red+Blue Ruins.  This explains why there's not very many monsters left there in Saga.  Blizzard Level: Over northern Uru.  Final two levels, inside and around Shelcoof: the mountains north of Uru, now the Forbidden Zone and Georgius.
     -Most of the bosses from Zwei are named in Saga.  The clawed creature from the forest is the Golia; you can pick up bits of it in Saga, in the Red Ruins in the Forest of Zoah.  The Sea Chicken is called, quite simply, the Guardian.  Also named are the Blizzard boss, and the Guardian Dragon; when Sestren does its "Fusion" attack (i.e., something like "Fused Shellcoof"), it names what it's summoning.  The evil dragon from the first Panzer Dragoon is the D Type 02.  The blue dragon (normal class Solo Wing) is D Type 01.
     -The town Lagi and Lundi are from in Zwei will look familiar-it's the Village of Cainus.  Boy, that place gets trashed by monsters often.
     -If you come back to the Excavation with a Light or Solo Wing, you can destroy the fans that made up the wind net, and get some unusual items.
     -If you watch the production sketches over the credits of Zwei, you'll see the gates of  the Imperial base in the Garil Desert.  Look closely at the symbol right above the gates-it's the insignia of the Black Fleet!
     -For Panzer Dragoon veterans, all the classes of the Solo Wing will be familiar.  Normal is the dragon from PD One; Spiritual is the evil dragon from PD1; Agility is the Sky Dart from Zwei; Attack is the Glide Wing from Zwei; and Defense is the Brigade Wing from Zwei.
     -As mentioned before, there are some recurring characters, either directly or obliquely.  The Emperor and his Admiral had a part in all three games.  While Craymen was apparently not present at the Garil Desert base when it was trashed, he was probably aware of it.  Gash comes in somewhere between Zwei and One.  And, of course, it's the same dragon in all three-Lagi.
     -After your first bout with Grig Orig, check out the letter Craymen leaves at Azel's side.  He signs it "K. F. Craymen".  That makes his initials "K.F.C.".  You can't tell me that wasn't intentional.
     -If you've played the first Panzer Dragoon, you know it's pretty vague on story.  A Panzer Dragoon anime movie was made covering that first game.  If you want to understand what happened, find the English translation in a video store-it's a big help.  It's short, but it explains the game nicely.  (Just try to ignore Kyle's voice-acting.  It sounds like they yanked some poor random sap off the street, shoved a script into his hand, pushed him into a sound booth, and then told him to act.)
     -The Black Fleet has been re-built twice before this game.  The first time was after Zwei, where Lagi and Lundi trash its Garil Desert home base.  The second time was after Panzer Dragoon, when the dragon (against Kyle's wishes, according to the movie) destroys the fleet in the air.  The flagship has only been rebuilt once, after the first game/the anime.
     -The dragon actually does use his claws and teeth in battle, although both are in the anime.  The first is when Craymen's predecessor, under the control of the Tower, attacks Kyle.  This is after Kyle pulls him out of the wreckage of the flagship.  (Nice save, Lagi!)  The second is when the D Type 02, already defeated in the dogfight, refuses to release Alyta and die.
