Dont larger maps have more wildlands by default? I get what you are going at, larger ones that actually feel like vast wastelands, but I also like to have many around dotting the world.
Maybe have an option between large, few ones, and small, many ones. Or like just one of them gets really large and is the main wildland of the game map.
As for the cut the world in half... while interesting, how would that go? A massive corridor wildland, or like the world is an hourglass and the block is in the bottleneck? (regarding that, less pangea worlds and more irregular, diverse worlds)
Maybe you CAN circumvent it, but it takes a long way so you either decide to move around it at cost of efficiency, or take it and get a shortcut maybe.
Would also like some better rewards for clearing. I admit I have not seen all of them (I WANT TO SEE THE SNAKE! DX) but most have as a reward a city and some shards, and while thats awesome in some of them, like the one that is all crystal-ly in appearance (Forgot the name) and blue ground, which tends to have at the very least 3 shards on it, there is also the junkyard that feels so cheap.
One that felt cheap too was the Shroud, granted, Magnar took it before I got there so I jsut took it from him so maybe I missed something, but the city is just cooler looking and a pair of life/death shards? The description said it had treasure. (Again, maybe Magnar got it, will check)
Sorry for going a bit off topic, but felt it related a bit.
