Broken Sword: The Serpent's Curse

Played via a point and click or touch user interface, the player guides protagonists George Stobbart and Nicole "Nico" Collard, who at the beginning of the game meet by chance at a Parisian art gallery, where they witness a man disquised as a pizza man murdering another man and stealing a seemingly worthless painting. George and Nico then get thrown in an investigation and travel to various locations. Source: Wikipedia, "Broken Sword: The Serpent's Curse", available under the CC-BY-SA License.
