Seriously.. they are made just with 1 block and look horribly simple and make no sense , how do they get to the 2nd floor.. and why are they made with jus tone block... its like a newbie made them.... everytime i find one on the planet it makes me rage!! #firstworldproblems please use at least a few blocks to design the homes..
Personally I like the simplicity of the houses. It made me feel like these guys are primitive and build strictly on the ability to survive. Though adding stairs might be okay. The idea of them hopping up onto the windowsills to get up to the second floor is oddly hilarious. Though I wouldn't mind them having furniture in their houses as well.
there is for sure a way to make it still look primitive and interesting with more then 1 block. technically the block used is showing craftsmanship of being able to cut wood into planks and use nails to hammer them together... i'm saying you could at least use a few addition blocks to make it look good why is everything 2x2 also.. its seriously like they just designed it in 3 seconds.
Considering that these changes have been in Nightly since June 16th (source 1, 2, 3, 4) and you made your request on June 23rd (source), I really don't think you had as much of an impact as them just redoing the biome altogether. Only problem with the changes, IMO, is that it's difficult to find a Agaran merchant now.
