Crystal Tools is a game engine created and used internally by the Japanese company Square Enix. It combines standard libraries for elements such as graphics, sound and artificial intelligence while providing game developers with various authoring tools. The target systems of Crystal Tools are the PlayStation 3, the Xbox 360, Microsoft Windows and the Wii. This was decided with the intention of making cross-platform production more feasible. The idea for the engine sprang from Square Enix's desire to have a unified game development environment in order to effectively share the technology and know-how of the company's individual teams.
Crystal Tools entered development in August 2005 under the code name White Engine. It was intended for the PlayStation 3-exclusive role-playing game Final Fantasy XIII, while it was first showcased in the Final Fantasy VII technical demo for the PlayStation 3. The decision to expand Crystal Tools' compatibility to other game projects and systems marked the official project start for a company-wide engine. Development was carried out by the Research and Development Division headed by Taku Murata, which was specifically established for this purpose. As Square Enix's biggest project to date, the creation of Crystal Tools caused substantial problems in the simultaneous production of several flagship titles; various critics cited the engine as the primary cause of significant delays in the release of Final Fantasy XIII.
