What is an SG3 file?

SG3 files mostly belong to Game Editor. These SG3 files are game resource containers used for storing internal data in several strategy and simulation titles.
In Age of Mythology, they store sprite graphics. In games like Caesar III (often seen as Pharaoh game data files) and city building games from Sierra and Impressions Games, they hold 3D models and other game data.
Key details as outlined by FilExt.com include:

Age of Mythology sprite assets: SG3 files keep the visual components used for characters and items. For more details, visit the Age of Mythology page.

Pharaoh game data: They contain models and textures essential for game environments and units in Caesar III and related Serious Games.

Sierra game data: Some SG3 files serve as internal containers for assets in city building and simulation games developed by Impressions Games.

FilExt.com note: This format is specific to the game engines that created it, so opening or editing these files usually requires specialized game editors or mod tools. It is wise to backup originals before any modification.

ChessDB (Game File) by Dr. David Kirkby
ChessDB is a database program used for storing chess games. A ChessDB format database consists of three files: .SI3 (index file); .SN3 (name file); .SG3 (game file) (those 3 are needed to make one database). These are all binary files. Some complete databases are held on the ChessDB web site. At the time of writing, one database (called 'huge') has over 3.5 million games. Other files used in ChessDB are: .PGN (Portable game notation, which is used in lots of chess programs, so is not unique to ChessDB); .EPD (Extended Position Description); .SSO (Search options file); .SOR (Repertoire file); .DAT (used on four files - engines.dat history.dat options.dat and recent.dat) to hold configuration information. All are text files. This file format is classified as Database. Related links: ChessDB Programmers Reference
