but has nothing specific to shooter.

Really? One of the statements is literally:

In the game, it is fun to shoot someone in the head *

Honestly the whole first part of the survey is completely flawed. It's asking you to provide your response to gaming as a monolith without allowing for nuance.

For example:

I like the violence in the games, the more the better * Strongly Disagree ... Strongly Agree

Your answer has to range from "I love the violence" to "I hate the violence," but doesn't even consider if violence is present in the games you play at all. "Strongly Disagree" could mean "I hate the violence" or "I don't mind the violence, but it isn't present in the city builders I spend all my time on."
