Not to discourage you, but I have learned some things from my experience of maze building.
Mazes are cool and all, but for most players, once they finish the maze, they are done and don’t return to the server unless there are things to do beyond the maze.
I think there is a limit to how much patience people have for being “trapped in a maze”. It might be enticing if it has a variety of sections and styles, but crawling thru a traditional blocky maze for a whole server does not sound appealing or fun. My biggest creation involves normal mazes, plus a boat maze, a sky island maze, a scavenger hunt, a handcar maze, and more. Just to give you some ideas. If you made something with a variety like that, I would definitely give it a go. (bear in mind that took about 6 months to build with over 5 helpers and covers about half a 1x server)
