I mean, it certainly speaks to patience. I bailed on my 6x6 college mapgen after about two weeks. That said, going with what you know is understandable.
If you’re really interested in making locations, I’d encourage you to dive into the json files. It’s not really coding, and people always say ‘bah, I can’t learn that’, but it’s actually very easy.

And if I ever have time for editing, I’ll be posting a let’s mod series on Youtube sometime in the next month or so where I’ll cover a lot of the basics in as plain of english as I can manage.
I would, however, discourage you from making locations that are 300+ tiles. x_x
