I don't think it exists, but I'd give anything to up the draw distance for MM6-8. You could probably render the entire world and every monster in it on modern PCs. Would love to see that.

I think areas are separated into zones, so not the ENTIRE world, unless someone glued them together in a mod.

But yeah, the whole zones, maybe.

It's not something that's in a settings option anywhere.

The only place that this would be possible is within a patch, and as far as I know it isn't in any patch.

It would be cool though.
