What would you think about a map extension to the south?

So I was fishing at the great river down to the map boarder while checking out the structures on the other side of it which you can't reach.

I feel like the game world, especially in RDO is a bit too tame. Also the desert region is kinda small in my opinion. You know every corner of it pretty fast.

I would love to ride along desert canyons and get that wild west feeling. I guess mexico was around 1890 more wild than the US at that time. So the fictional mexico in-game could be more wild also, more wilderness maybe even more bandits which come randomly in that region.

That was just simply a thought I had.
