Last night while browsing an RPG PDF store, I came across a product that filled a niche so small I never would have thought of it on my own.

The PDF market’s low barrier to entry makes it possible to create micro-niche products like this, and there are quite a few of them out there. But how micro is too micro, especially when it comes to products for GMs?

For instance, how often would you need a kobold name generator?* Once? A genre-appropriate general name generator I could see being useful, but . . . kobolds?

As a GM, what’s your appetite for micro-niche products? And where do you draw the line?

* To the best of my knowledge, there aren’t any kobold name generators out there. Edit: And naturally, that would be incorrect.
