Yeah totally. At least give people some bloody credit.
For instance, I can tell you that I have had a short story published in a collection at my college.
I at least admitted to the class (it was part of a course) that I was a LOTR fan (which was 50% of the inspiration) and that I got my ideas from fantasy video games, themes, and series. Which is what each respected person would do.
However, I didnt mention specific ones because there might be an idea I copied. And I may have not heard of that series/game/novel, which would be diastrous for my reputation should I have had written and published a novel. It's quite a common thing many people overlook.
