Personally, i think that Wellington and Galebrook are getting really crowded and I almost couldnt find my house after i built it! So i think there should be more towns with their own style and NPCs, like a snow town or have shopkeeper NPCs that help noobs.
This game doesn’t need to be like Minecraft, because a similar game already exists and is called Minecraft.
Each server has its own economy, npc shops would destroy the economy of every single server, but you can always buy 1 silver for 3 feathers at newbie village if you want.
