While the title was written in part by one of the same writers as Ultimate Star Wars, Adam Bray, the two projects are described as being "very different." Readers will find "very little common information between the two" as "Absolutely Everything highlights anecdotal, quirky and obscure facts." On October 3, 2017, the title was followed by Star Wars: Absolutely Everything You Need to Know, Updated and Expanded.
Star Wars®: Absolutely Everything You Need to Know explores the world of Star Wars through lively lists, interesting facts, and questions and answers via a highly engaging infographic design. Whether it's a chart of who is the oldest Jedi, a list of all the owners of the Millennium Falcon, or a diagram showing all the Jedi Yoda has trained, this guide will excite readers of all ages and provide facts they never knew about the Star Wars Galaxy.
