Hiya!
Hardy-har-har, guys.

I get it. I'm an old fart set in my ways... I did mention my Grognardia Curmudgeonitis, didn't I? I'm fully aware that my particular "tastes" for how a D&D product should be made are on the, hmmm, lets say "crusty deep-fried edges", but I've simply accepted it. I speak up about these little things often becuse I know WotC folks pop in here from time to time and just want them to keep striving for perfection. If all they heard was how happy the unwashed masses were with their product, they'd never try anything difference.
The books don't have to have much in them to make a difference. All it takes is one little "thing" or "word" or "look", and the message is changed. The title is enough, more than enough, because a title should embody the theme of the work. At least IMNSHO.
Basically...yes? As I said in the paragraph above...all it takes sometimes is ONE little thing; and having the title of the book be "[Proper Character Name]'s, [brief description]" sets the stage from which the entire perspective of the book is to be viewed. If it was called "Tome of Foes" it tells you it's a book with a bunch of bad guys that a DM can use in his personal campaign. "Mordenkainen's Tome of Foes" tells you it is a book about how
Mordenkainen discovered, wrote about, saw, encountered or otherwise "was involved with" a bunch of bad guys the DM can use in his personal campaign. In the later, that tiny little thread, however ephemeral, "connects the foes, and thus the DM's personal campaign, to Mordenkainen and how he saw/sees the foes". It doesn't matter if there are ZERO mentions of Mordenkainen at all in the book. The damage is done with the name in the title. First impressions and all that I guess...
Anyway. Carry on poking fun at the old guy in the back. I can't hear you anyway...
