I want to grant items or virtual currency if a player watches my own videos in my game. But I just want to grant rewards if the player has watched a video for the first time. If the player watches a video the second time, then the player receives no rewards.
For example:
1) I want to create an introduction video where I show and explain the controls of my game. This video should be available for all players when I release my game.
2) Some time after the release of my game, I want to add new videos where I show DLC content and updates that will be released at a later date in my game.
Where can I upload the videos? Would it be possible to upload the videos in my PlayFab account?
Is it possible to use rewarded ads for this purpose?
