I want to start a construction project in Minecraft in Survival, I'm just unimaginative and want to get some ideas.
What can you build in Minecraft on an approximate area of 500x500?
Eiffel Tower
Convert the village into a town.
Space X Super Heavy Booster and Starship
You can build the whole launch system
That in smaller
Maybe an ancient city? I always find it very beautiful and impressive when people build ancient times because I'm very untalented in building in Minecraft. But I could imagine it very nicely.
