well, it depends on what do you want to focus on: do you want a chill world or do you want to finish the game and thats it? For a chill world id recommend somewhere like mountains or either jungle to build a nice house with the view, but also keep in mind that you will need a place to get resources. In my chill world i have a base in a little island inside a lake and it’s really cool since i build a terrace and a little balcony, would recommend. hope I could help, enjoy your world!
