There is only one issue, my sister got ahold of it and ended up opening it up so she could play it. T_T So if you wanted it for the game I can look at your list, but if you wanted it because it was sealed it is no longer sealed. xD
Thats the same reaction I had as well. T_T Oh well, I tried not to be too hard on her considering she couldn't have known the value of a sealed GC game like that. I guess I should give it a play through now though. xD
Here is a list of the sealed ones I have (All BL too):
Atelier Iris 3 (First print, I know cuz I bought it at release)
Kingdom Hearts: RE Chain of Memories (black label)
Odin Sphere (black label)
Shin Megami Tensei: Persona 4
Tales of the Abyss
Tales of Legendia
Wild Arms 4
Xenosaga
Xenosaga II
Xenosaga III
