I'm also getting tired of these maps now, when you play the game for a longer period you know all the places and tricks. When new maps get added every players knows the same about the map.
Keep in mind that making maps is not a thing that you do in a couple of hours tho. First you need to think of a theme, what you will be using for the map. Second is that you must think how big it should be. Then you need to place generators, the egg and the villagers in a good spot. Last but not least: you need to make sure if it is a map that won't be boring, decide if it fits in and is playable.
