My impression is that most newer (and also many old) machines are tied to large franchises such as movies or rock bands (e.g. the Hobbit, Ac/DC etc), whereas quite a few older ones are not (e.g. Theatre of Magic, Centaur etc.). So what are the newer machines (say less than 10 years old) that don't have any attachment to a franchise? Big Juicy Melons is the only newer one I can think of that actually works.
