I'm confident in saying that the Infinite and Flat World types are the more commonly used ones, however I'm sure that some people, even if it's just a few, are somewhat disappointed by the news of this removal. If you're part of that group, I have generated 50 Old Worlds for you to download and use!

I didn't look for any specific worlds, just going with the first 50 I generated. As such, I believe that most if not all of these are unbeatable, but I hope they provide interesting survival experiences. At any point you can turn these worlds into Infinite worlds by scrolling down in the world options screen to where the export, copy and delete world options are, so if you get tired of living in a limited space, you can make the world much, much larger.

Note: If you do decide to make these worlds infinite, the generation and world height will stay as they were in 1.17. I'm sure there is a way around this, but I haven't found a solution which is entirely functional. I will update the page if I do find something though.

The worlds shown in the screenshots above from top left to bottom right are: 13, 15, 3, and 24! Even though I just went with the first 50 and didn't search for anything specific, I still managed to end up with some interesting worlds!

The .mcworld files in the zip are simply named "Old1" to "Old50" because I just numbered them as I made them. I also have preview screenshots numbered 1-50 so if you think I should include all the preview screenshots in the zip or on this page, let me know and I'll add them!

I did attempt to release this back in December, but forgot about it. Whoops!
