Matthew Settle's opening narration credits "the latest in video game technology" for the cgi battle reenactments, and the closing credits include "Total War Graphics by The Creative Assembly". In fact, the graphics are produced using the game engine from Rome: Total War (2004) (VG), a strategy game produced by The Creative Assembly and published by Activision. The same process is used for the BBC game show, "Time Commanders" (2003).
