The actress who played Nico, Sarah Crook did not actually audition for the role. She was one of the supervisors of the audition, and asked Charles Cecil if she could try out for the role after a string of applicants Cecil regarded as unsuitable.
This series provides examples of:
Breakthrough Hit: Revolution has been recognized because of the first two games.
Contest Winner Cameo: Two contributors from Kickstarter campaign, Kat and Adam make appearance in The Serpent's Curse as Nico's neighbours and as beta testers to the game.
Also, a lot of the random junk you could examine in the original is taken out in the Director's Cut, averting it here as well. A lot of the time, it really is just some funny observations or unimportant descriptions. But an entire character gets cut at one point.
At one point in Sleeping Dragon you find a "large iron key" twenty feet away from a "large iron gate". Response to using one on the other: "There was no reason to try that"... A Red Herring is one thing, but you'd think it could at least get a unique line of dialogue.
Franchise Zombie: The series had originally been designed as a trilogy with The Sleeping Dragon intended as the finale, but fans persuaded to create another sequel which was The Angel of Death. The fan reception, however had negative to mixed reviews after it's release.
The Other Darrin: Several secondary characters whose original voice actors were either dead or unavailable.
Most notable is Nico's English voice. She has been voiced by a different actress in each game: Hazel Ellerby in The Shadow of the Templars and Director's Cut, Jenny Caron Hall in The Smoking Mirror, Sarah Crook in The Sleeping Dragon, Katherine Pageon in The Angel of Death (also known as Secrets of the Ark), and Emma Tate in The Serpent's Curse.
Talking to Himself: In the second game, Rolf Saxon also voices as a goat in Quaramonte City.
In Director's Cut, Hazel Ellerby plays both as Nico and Imelda Carchon.
Write Who You Know: One of the minor characters of The Shadow of the Templars Albert the Concierge was inspired by a concierge who shouted Charles not to make so much noise in forecourt at night and then started ranting about the English.
