I agree with Darlxx here. I don't think they were going for realism. You also didn't really give any ways on how the hub could be improved. You just talked about how the assets were bad. Some of the best builds on CreativeFun, maybe even Minecraft, are not even realistic. They are fantasy...
I am great at medieval builds.
I know many commands for world edit, though I do not dominate in it.
I have been building for about 4-5 months.
I have made buildings for start-up servers, though left many servers due to owners abusing powers.
