Saw it, but didn’t comment there as it would be slightly outside the scope of that effort. Here, though…
Would that open up for other geographically based changes, such as the introduction of new kinds of terrain and biomes as you get further in some directions?
There’s also the other issue of why you’d want to plunge deeper into mega city hell by going east. It just makes one direction decidedly less desirable than the others (unless your flavor of fun is to kill endless numbers of zombies for no other reward than random junk you’ve already acquired to over abundance from the hordes of zombies you’ve already killed), and that’s in a situation where route availability is already limited by water and limited presence of roads and usable bridges.
