Hammer Game Configurations
The Game Configurations options (in the Hammer Options Dialog) allow you to set up game profiles, each of which contain a number of modifiable elements, including texture format, map format, game entity definition file, defaults, and file and directory path location information.
This is a list of the preset game configuration profiles (Half-Life, Counter-Strike, Day of Defeat, etc.), or custom profiles you've created, for which you can edit the properties. The information in the Game Configurations tab reflects the currently selected configuration profile.
Click the Edit button to modify the list of game profiles. The Edit Game Configurations dialog will appear. Click Add to create a new, blank game configuration. Click Remove to delete the selected game configuration. Click Copy to make a duplicate of the selected game configuration. Click Close to close the dialog and return to the Game Configurations tab.

You can specify here which FGD data file Hammer will use for entity support for this game profile. You have the options of adding, removing, or editing the game file. Click Add to add an FGD data file to the current configuration. Click the Edit button to launch the default Windows text editor and open the selected FGD data file for editing. Click Remove to remove the selected FGD from the list. See the FGD for more information on the contents of FGD files.
