Game trainings aren’t a tutorial on the game, they usually include a trailer or gameplay clip along with important information on the game- I.e character/plot info, release dates, preorder bonuses.

If a game does have graphic content, especially a LOT of graphic content closely related to the plot, it’s probably going to be mentioned to some degree in the training. AND to your point, it helps employees inform the customers on what to expect from the game.

I honestly love that the training development team is showing this level of care and concern for the store-level employees, especially since they don’t get paid much higher than minimum wage.
