Via Rose: A trailer and character voice previews for the first release. And the range from BF.
An interesting choice here - audio gives the immediacy of drama and the budgetary freedom of fiction, and Big Finish know their way around the dialogue-as-description issue that audio drama often has thanks to years of Doctor Who and more. And being a British company the signature/iconic characters mostly sound British apart from the slightly American fighter, in classic Hollywood fantasy style.
(And yes of course I've thought of doing games as audio plays.)
