The picture says that Doom 3 derieves from original Doom engine. It's rather the successor of Quake3 engine. Also the small letters are almost unreadable. —The preceding unsigned comment was added by 83.23.188.17 (talk • contribs).

The Engines of Quake 1 and 2 are retroactively referred to as "id Tech 1" and "id Tech 2" (http://en.wikipedia.org/wiki/Id_Tech), while Doom 3 definitely has a connection to the "Quake Engines" (also referred to as "id Tech 4"). The Call of Duty 2 Engine (called IW Engine 2.0 http://en.wikipedia.org/wiki/IW_engine) is also based of idTech 3. The "Battlefield 2 Engine" is called "Refractor 2" (http://en.wikipedia.org/wiki/Refractor_Engine). "Frostbite" and many others are missing. Is this a diagram about engines or about games? The categorization has no source whatsoever and some of the mentioned engines do not even fit the given description. I would recommend removing this diagram completely as it is extremely inaccurate and incomplete. — Preceding unsigned comment added by 95.91.201.76 (talk) 20:09, 16 September 2014 (UTC)
