Emacs is a great game

Emacs is an extremely customizable software. It's not just a text editor. Through config file and package manager you can add a lots of things, even if you are not a programmer. I can't write code, I am too dumb for it, but I like to tinker with stuff, so I occasionally mess up my init.el file. I am using Emacs for a few years now. I generally have good relationship with it, because I don't ask much. I learned it through what I need. First a markdown editor, then I looked at other things it can do, and it opened my eyes to org-mode. Then I blogged not just in markdown, but via org too. I use it for reading too, it can be an ebook reader, but I use it for RSS. Emacs is puzzle itself, and you can lost in it. Not in the style of The Witness or The Talos Principle (which is now DRM-free on GOG, btw), but you will understand when you get there.
