Создал мод на SE2013, через батник запускается а через стим не хочет!
Вот gameinfo:
"GameInfo"
{
game "MyMod"
title "MyMod"
type singleplayer_only

FileSystem
{
SteamAppId 243730 // Source SDK Base 2013 Singleplayer
SearchPaths
{
// No /custom/ folders because they can interfere with mod content and shouldn't be in mod gameinfo.
game+mod+mod_write+default_write_path |gameinfo_path|. // Mod
gamebin |gameinfo_path|bin // Mod's Binaries

// Base Half-Life 2 Content: ep2, episodic, hl2

}
}
