Complete Gameplay of a game (at least main story + interesting sidestory) similar to a movie. Boring parts (like grinding, farming & getting collectibles) are omitted.
Prerecorded. To ease my ISP and PC load it will be shown when I'm asleep / not at home; therefore usually no interactivity possible.
Shown either in one part or (for long games) in several parts.
Either only showing the beginning of a game or playing a part of it. Can be live, can be prerecorded.
