If that's Zeph's store, then Zeph's store is coded really shittily.
PHP Code:
new GAME_CSS = false;
new GAME_CSGO = false;
new GAME_DOD = false;
new GAME_TF2 = false;
new GAME_L4D = false;
new GAME_L4D2 = false;
Like, the fuck? First off, use new syntax. Jesus. Secondly, why use these ints set to false? Shit don't make sense. Just use EngineVersion and grab the game type that way.
