From the looks of it, yes.
A texture replacement could fix it i think. But i'm glad there are biomes now, even if not completely accurate at this point.
Also, there are too many small rocks generally on the surface of the Earth in OT imo, but thats something that can be tweaked.
Minecraft style gameplay with vehicles and planes would be awesome.
The cool thing is, the scale is big but the "map" is not infinite in OT. Imagine you had a base with a dozen or so players, and a group would decide to make an expedition to gather some rare resources.
They would have to explore and travel for a couple of real world days, to reach the location of the desired resources and then return to base. Meanwhile, those who stayed at the base would expand it and build and craft there etc. Would take some coordination and it would perhaps instill a sense of adventure. And when groups of players are scattered around the Earth, a war would not occur that easily at first.
Kind of what i thought of when taking these pictures, lol.
