I'm not sure what you mean, but by default there's no seperate scoring for one game. You need to copy that game and then add the gameserver to the copy. I've copied the game CS:S by myself and added to each copy one server.
It is also possible to add new gameservers, that uses the supported log formats.
If you want to add a new game, execute this query to your database:
Code:
INSERT INTO `hlstats_Games` (`code`, `name`, `realgame`, `hidden`) VALUES
('notg','Name of the: Game','notg','1');
Example with Counter-Strike: Source:
Code:
INSERT INTO `hlstats_Games` (`code`, `name`, `realgame`, `hidden`) VALUES
('css','Counter-Strike: Source','css','1');
After that just start adding actions, weapons, etc..
