I must admit, when looking online for how a building or town looked specifically, I always found the Minecraft version of said build or town. For some reason, I felt exactly what you do: like I was just the next person to recreate Hyrule.
the thing is, just because its been done doesn't mean I don't enjoy it :) At that rate, people craft wonderful duplicates of art, build computers, purchase pets, play the same games... yet other people have done them all a thousand times before.
There's also the fact that I'm growing a community that can watch Hyrule be built from the ground up rather than someone saying "Okay, here's the finished work, admire it in this 60-second clip!"
I have had it postponed for a little while now, but I do plan to pick it up again at some point in the future!
