yeah its the Culture Shock through The City Dares not Sleep or something pack
That's be the entire franchise pack :)
Season 1 - Save The World! (6 Episodes)
Season 2 - Beyond Time & Space (5 Episodes)
Season 3 - The Devil's Playhouse (5 Episodes)
Doesn't include Hit the Road (the old LucasArts 2D game that spawned Telltale Games), but it's a very awesome collection.
