How to add variables to H1s in video game posts?

Yes, you read right; How to add variables to H1s in posts?

I recently added the word Play in the Title Tag to show the intent of the posts in the SERP.

However, I notice that the video game titles don’t show the intent of the post. Those who arrive read the name of the game but don’t know if it’s a game, a review or something else.

I guess you’ll understand the importance of putting the word Play in all the posts where I have games. Currently all posts (15’000) are games.
