Effects of modern culture (Movies/Gaming) on karmic reactions

Having read the following: https://buddhism.stackexchange.com/questions/10247/are-actions-in-computer-games-bad-for-karma Background: I have watched the latest Doom Eternal gameplay, its brilliant in terms of Graphics and dynamics. The actions and details are more "real" than ever before. I used to be a fan of the doom franchise and enjoyed the game like any other gamer. Having touched Buddhism, it is the first time I question the origin of these games and the effects it brings onto the players, from a karmic perspective. I never had such thoughts and questions before I learned about Buddhism and the Dharma. My question: 1. What would be Theravada's take on this issue? If we know the in-game "killing" isn't real, will this create any negative karmic effects? 2. From a hypothetical perspective, are these cultures being carefully prospered by the ruling class of this planet to keep individuals chained to Samsara for as long as possible?
