I intend to download a Minecraft map someone has made that looks like a city and change my character to look like an engineer, ideally a civil engineer; although, civil engineers don’t have any particularly iconic attire as far as I am aware. I will then go through the city and basically pretend to inspect its infrastructure, after which I will give it a grade. I expect the infrastructure to mostly be things like highways and sewers, but maybe the map will come with a dam or maybe I could make one, it largely depends on whether I feel it’s necessary at the time.
Alternative:
I could grade people’s stuff on a multiplayer server, though this would be a bit more difficult to adequately record any would rely on their cooperation somewhat.
