Okay so I was looking at the Epic Games Launcher that I downloaded so that I could start to do some game designing and I’m a little lost and don’t know what to download to make my own maps for really nothing. like I dont want to make it for any game I just want to practice without downloading a game to be working on. Please help if you understand where im coming from on this topic.
Install the latest version of Unreal Engine. That is all you need to create your maps. However I would recommend installing some free content packs (also available from the launcher) so that you have some models and props to start with.
