EA has tried this before, with predictable results. In 2020, EA Sports UFC 4 included full-screen ads for the Amazon Prime series The Boys that would appear during ‘Replay’ moments. These were absent from the game when it launched, with EA introducing the ads about a month later, thereby preventing them from being highlighted in reviews. It wasn’t long before the backlash led to EA disabling the ads.
You can’t really sell ads on a per impression basis with just product placement. They want the ad sales to be recurring revenue.
