Following "Far Cry"s release, Crytek, wanting to show that CryEngine had other applications, signed a deal in July 2004 to develop a gaming franchise with publisher Electronic Arts (EA), a direct competitor to Ubisoft. This franchise became the "Crysis" series, and through which Crytek continued to improve their CryEngine. With Crytek unable to work with them, Ubisoft assigned its studio Ubisoft Montreal to help port the title to the various game consoles through the "Far Cry Instincts" and "Far Cry Vengeance" titles. These titles required Ubisoft Montreal to rework much of the game as the consoles at this point in time were not as powerful as personal computers, and could not handle the wide open levels without performance problems. These games created more linear levels from the original "Far Cry", added campaigns and multiplayer modes, and in some cases, changed the game's narrative to less-realistic outcomes. In March 2006, Ubisoft acquired all rights to the "Far Cry" series and a perpetual license for the CryEngine version used in the development of "Far Cry". Ubisoft Montreal remained the principal studio developing all future "Far Cry" games.
