What are your opinions on using real people from history (recent or far past) as characters in fiction? Do you find them more or less interesting as characters to read about. For example in Phillip Jose Farmer's Riverworld series, everyone from all of earth's history is resurrected on an a planet covered by a seemingly endless river valley. The main character for the series is Sir Richard Francis Burton and he meets many other minor and major characters from history. I've been developing a MC (right now he is a real person from history) for a time travel novel, and I have been toying with whether or not I should include more real historical characters, or just create fictional historical characters for my MC to meet.
