Well yeah, but those would probably be the most prominent ones. I suppose there would also be more forensic/detective oriented gadgetry too, but I can't imagine it being too expensive. And as for the more colorful villains, I wouldn't want them to be overexposed. Not that the series has to be like supervillain-free like a lot of live action shows tend to be, but I'd like their appearances to be a big deal. Most episodes would deal with Batman fighting more real world crime and the mob, or maybe corrupt businessmen, then a few episodes would deal with the Joker or Riddler, for example. One thing that I would like established is that this isn't a normal world. Weird things do happen sometimes, things that are otherworldly or at the very least, improbable.
