Huh?
Well plagiarism is when you steal/directly copy another person's work. So, if you had a certain game in mind and modeled your mod off of it, while you may not directly or actually steal anything, the fact that it's so in your mind and directly influences your design choices, you as well as did steal ideas.
Think of it as writing a term paper, and you read some sources, and you don't directly steal anything from your sources, but you accidentally type a sentence almost exactly like one you read. You didn't do it intentionally, but you still did.
