Legend
As @Ash Mantle pointed out, there is a lot out there in other supplements / adventures that are official WotC products that are not strictly for players. Of note: there have been no new classes or feats yet (just archtypes, backgrounds, races, etc.); however, the up coming Eberron book will provide the Artificer.Thanks @Ash Mantle those descriptions help.
The group is largely meat-and-potatoes when it comes to races. Exotic races aren't appealing. I don't know about the other players, but for things like Backgrounds, I tend to find pre-published backgrounds to be limiting, so I usually make up my own. It sounds like I don't need things like "Curse of Strahd."
In fact, except for the lack of classes it looks like there is almost enough for another PHB spread out amongst other books. I hadn't realized that until reviewing Ash's list
