This might seem kind of nit picky but I don't like it when quest mods reference characters in the base game. It usually just comes off as "Look, I acknowledged that this character exists! See how cool that is?". I can't quite put my finger on it but it always seems off when they do. Usually if it's a character that's famous in the Mojave like Caesar or Mr. House, then it generally works fine, as long as they're just mentioning them, not breaking their character. But when they bring up a minor character like Julie Farkus or Violet, then it just comes off as forced. Now in the proper context, it can work better. For example, in the Delilah companion mod, she talks about Doc Mitchell and Sunny Smiles. She lives in the same town as those people, so it makes sense that she'd bring them up in conversation. But when a character brings up another non-mod character, and their only relation is what they tell you, then it just feels awkward. Does any of that make any sense?
