Well I should throw in some suggestions now...

Board Game Designers VS Video Game Designers

Brutus VS Lee Harvey Oswald (Assasinations that took down leaders)

Christopher Columbus VS Neil Armstrong (Discoverers of New Worlds)

Hammurabi VS Judge Dredd (Judges that contain harsh punishments for strict law)
