Makes me wonder, if they do start to incorporate things of FF's past, how we could see something like Doom Train play out. I honestly would forsee that playing a role in the Garlamaid (sp?) areas, something of an instance you have to complete to get further into the region, ultimately fighting the head of the train to progress into the next region.

Which, on that idea, I'd like to see something like that.. old FF games would make you go through a cave, or a dungeon in order to progress in the world, afterwards you could usually explore the surroundings at your lesiure.

I sort of imagine DW belonging to an ancient castle in Ishgard somewhere, along with the Yellow Dragon. Possibly as a Sub and then Main boss scenerio.

Ultima though.. that still has my curiousity piqued.
