I was just thinking how cool it is that there are a couple games on NES that have the entire overworld of a prior game represented, and it's even cooler when the original maps are totally dwarfed in the follow-up. It makes you think "Wow, I felt like I was exploring a vast world before, but it was actually just a little speck in this much bigger world?"
Take, for instance, the representation of the original Zelda map in Zelda II:

And the entire world of Dragon Warrior (the squarish cluster of islands) in Dragon Warrior II:

I'd love to know of more examples of this, from any system, and pictures would be grand.
