This is the crux of the subjective term of "done" so I take the conservative approach. Any content or update that substantively changes or adds to the game is considered content that needs to be present to be considered done. Maps, dlc's, changes to a story, are all considerations to that. Simple bug fixes and patches do not. Effectively the basis of the site is to answer the question "If I play this game now, will I be getting the complete and total gameplay experience."
