There is a difference between boxy an undetailed versus lazily made and ugly. This is the latter.
Afghan DM is boxy and undetailed, it really is. It's just sheer size that make it such a great build.
Another good example is Rky's TDMs, which are very boxy and undetailed yet extremely functional and easy on the eyes.
This is just lazily built, and I love how you try to say "It's good for slow computers" even though it's on a terrain-filled map. Way to make stuff up to "compensate" for your poor building skill / laziness.
