Uncharted: Drake's Fortune is a 2007 action-adventure game developed by Naughty Dog and published by Sony Computer Entertainment. It is the first game in the Uncharted series and was released in November 2007 for PlayStation 3. The game follows Nathan Drake, the supposed descendant of explorer Sir Francis Drake, as he searches for the lost treasure of El Dorado with journalist Elena Fisher and mentor Victor Sullivan. The development of Uncharted: Drake's Fortune began in 2005, and saw Naughty Dog altering their approach to development, as they sought to create a humanized video game that was distinct from their other entries, settling on an action-adventure game with platforming elements and a third-person perspective. The team regularly updated or wholly changed various aspects related to the story, coding, and the game's design which lead to delays. The development team found influence for many of the game's aesthetic elements from film, pulp magazines, and movie serials. Extensively marketed as a PlayStation exclusive, Uncharted: Drake's Fortune received generally favorable reviews, with praise for its technical achievements, cast, characters, story, music, and production values, drawing similarities to blockbuster films. It faced some criticism for its graphical issues, short length, vehicle sections, and marked difficulty. Uncharted: Drake's Fortune sold one million copies after ten weeks of release. It was followed by the sequel Uncharted 2: Among Thieves in 2009, and was re-released on PlayStation 4 as part of Uncharted: The Nathan Drake Collection.
