Re: Wold Newton
Actually, my personal edits* tend toward the following:
1. Dropping characters/source material I don't know well or am unfamiliar with.
2. Dropping some connections to open them up for GM or Player use. FREX, I like to use the "core" families (Savage and Clayton) as ancestors of contemporary PCs or NPCs, so I edit the descending family lines accordingly.
*I call this "de-cluttering". (I also "de-clutter" the Champions Universe whenever I use it, albeit using different criteria.)
