I went to this page on Wikipedia which details the A to AAA video game (console, handheld and computer, but not phone app games) titles released in 2011, and took a random sample of 50 games from the list of 266. The question I ask is “Does this game feature killing (of any apparent living creature) as a key aspect of gameplay?
The results are similar to past results: 39 of 50 feature killing, a 78% rate. Previously the rate was about 80% as well.
Here are links to some of my previous research:
