I have one complete in absolute mint store condition. I also have the hardback full color guidebook which is even harder to find.
I'm looking for a complete Rhapsody, Valkyrie Profile for PSone games and on PS2 the LE Growlanser Generations or the Shin Megami Tensei: Nocture and Digital Devil Saga. Those are about the only things I'd trade this collection for.
Of course I'm not going to get all of those for it. I'd pair up Rhapsody and VP for the box set and guide book. Growlanswer Generations LE with guide book I'd trade straigt up. If you had both Shin Megami Tensei's I'd trade for those as well.
