Why is Arausio less famous than Cannae?

Why is the Battle of Arausio obscure while Cannae appears so often in books and films?

Cannae belongs to the famous Hannibal story, while Arausio lacks a similarly familiar central villain and is overshadowed by the political dramas that followed.

Memorable history often depends on a compelling central antagonist and a familiar narrative arc. Hannibal gives Cannae a famous commander, a long war, and a story that is easy to dramatize. The Cimbrian War lacks an equally familiar central villain for modern audiences. Arausio also sits close to the political rise of Marius, Sulla, and Caesar, whose later conflicts dominate accounts of the Republic's end. Its enormous losses compete with the Punic Wars before it and the civil-war narrative after it.
