Terry Pratchett is an author, primarily of the Discworld series of books. His daughter Rhianna wrote the BD novella (available in the D2:ED fansite kit) 'Child of the Chaos', covering the time period between DD and BD).

As for Venetica, I watched a gameplay video, but straight Action RPGs really have to do something unique to hold my interest for more than a couple minutes (I've stopped reading reviews mid-sentence when the term 'action RPG' was used).
