Complete and incomplete

Complete translation
A complete translation is a translation that has covered all of the main scenario's text. Optional side content may have been left untranslated. There may also occasionally be parts that were left untranslated due to engine difficulties or oversights.

In the case that the main game itself is not yet complete, then the translation can still considered complete as long as it covers everything in the latest development version.

Complete game
A complete game is a game that has been published for commercial sale in a finished form, or in the case that development is still ongoing just to add extra content, a game that has had its main scenario entirely implemented.
