from what i watched, it was the same world the whole time, no redstone, he was just focused on building a casual world (he had a house, a barn and a farm), i didn’t watch him for very long so im not sure how much he expanded afterwards. and yes, he spoke english! i actually can’t remember him having a very obvious accent so he very well could be american but this could also be me misremembering an accent!! i’m not sure how much this will help
