I figured I would just go the horse’s mouth and reach out to anyone playing ESO that will answer. I found a web-page that explains that if I purchase Elsweyr, I will get Morrowind, Summerset, and Elswey ( https://en.uesp.net/wiki/Online:Buying_Guide). Does that hold true today? Or was that a limited time thing? I see games on Ebay that still say this.
Also, with these chapters, how do we access the different content/chapters? For example, I played Neverwinter for years and could zone to other areas with a map showing all the zones. A lot of these zones were added with various expansions.
