Made this account for the sole purpose of asking this because it's been nagging at me incessantly that I can't remember what this game is.
**Note**: My memories on this are a bit iffy, I only got to play it when I rented it for a week back in 05/06 when my friend lent me his PS2
The gameplay was similar to Tales of Symphonia in that you ran around until you got into a battle and then once in the battle it was a free-fighting arena style battleground, the camera angle wasn't set though (you could look around and change the angles if I recall correctly).
It was a game on the PS2, There were two gods, both had avatars that were dragons, a white dragon and a black dragon respectively. You played as a (blue?) haired young male whos (girlfriend?) was the "Chosen" or "Vessel" and was slowly losing her humanity (thus another parallel to ToS in that aspect) you go on a big quest to save her and such. the bosses are dragons of different elements (pretty sure there were fire, water, earth, and air dragon bosses, at least the ones I remember) one of the two boss fights I remember is a water dragon you fight (at the bottom of the sea?) and it stuck in my mind because there was something along the lines of your father being one of the knights who sealed the dragons and he lost his life sealing the water dragon (you get his sword around this point, has a gem set in the pommel which was significant for some reason I can't recall, I think you might get it from beating the dragon) I remember one of the characters you can get in your party is a member of a human sized winged race (they had kinda fairy wings) and he was bad ass you could only get him if you could beat him and he was like 20 levels above any of your other characters at that point (for me he was at least, maybe I just didn't do enough grinding XD) but the other boss I remember was possibly the final boss (not sure cause I never got past him before I had to return the game and PS2) it was the black dragon god and it was intent on taking your girlfriends body as its mortal vessel and you had to go to its realm and fight it or something like that. The ONLY other thing I remember from it was that I THINK it was an Enix game (I seem to recall the logo from any time I started up the game)
Sorry I can't be clearer about it but if anyone knows what this game is that would be amazing and I'd love you
