Just hope they never add a gravity mod or those 2 towers are gonna topple
Seriously though I think it looks great. I was thinking I would make my Beta site similar to that to avoid the resources needed to protect a large sized base like my Alpha site. Mo'creatures = painful to keep safe from ogres. BTW neat tip...layer 127-64 = premium coal locations. I found digging from layer 60-80 (branch mining) landed me a ton of iron/coal which are the premium materials for me when building. Least till I get diamonds for tools on layers 5-16
I prefer to make all buildings out of stone/half stones and ground out of wood/cobble with my paintry pack it looks good.
*edit*
Here is my current setup.
The largest building = stables can fit 24 horses. Rest are basic storage/growing facilities. I was thinking next base I would make big but stack it to avoid having such a large area to clear. I have to clear the mountains at least 10 blocks to prevent ogres from spawning and destroying my base
I also put my nether portal in the mountain with a "Lava" floodgate to kill any mobs who come through. Its also small enough to kill ghasts.
I like it but I HATE the install for it...fails to work with me and when it does get installed I get odd GUI issues with certain blocks. I wish they had a more custom "pick and choose" setup like Paintry Pack does.
