If I run Primeval, and I might, I’ll probably use human history more than the series does. Only two episodes have really featured it. Sure, we’ve only existed for a tiny fraction of Earth’s history, but anomalies are getting closer together, so there’s a rationale there. Not as often as Doctor Who, but maybe once every six-to-ten-episode series.
And I’d definitely want the PCs to have trouble keeping a low profile. By way of example, tonight Matt did very well alone in Victorian London - imagine Connor and Abby stumbling around there instead.
