Here, I looked up one for Morrowind, as an example:
You may not cause or permit the sale, disclosure, copying, renting, licensing, sublicensing, leasing, disseminating, uploading, downloading, transmitting, or otherwise distributing any of the Products, the Documentation or any of the other components of the Package by any means or in any form, without the prior written consent of Bethesda Softworks.
In other words, you cannot resell the product with Bethesda's permission. Not that they had any intention of enforcing that, it's just a standard clause to cover themselves, much like the Steam TOU (a.k.a. the SSA).
Here's another interesting little tidbit regarding the editor:
If You distribute or otherwise make available New Materials, You automatically grant to Bethesda Softworks the irrevocable, perpetual, royalty free, sublicensable, right and license under all applicable copyrights and intellectual property rights laws to use, reproduce, modify, adapt, perform, display, distribute and otherwise exploit and/or dispose of the New Materials (or any part of the New Materials) in any way Bethesda Softworks, or its respective designee(s), sees fit.
In other words, any mods you make become the sole property of Bethesda, to do with as they see fit. Did they have any intention of enforcing that? No, and it's presence did nothing to thwart a thriving mod community. It was a simply CYB (cover your backside) clause to protect themselves from unforeseen circumstances. That's all an EULA is, to protect the rights holders from unforeseeable circumstances. This is why they're always written in such extremes, because they have to basically cover everything they can think of, and then some.
