People who play video games are more likely to be aggressive due to frustrating game mechanics rather than actual violence, a new study reports.
The Oxford research institute, which published the research, carried out a range of tests involving modded versions of Valve's ever-popular Half Life 2.

Some testers were given games modded in such a way that the controls were unintuitive or frustrating, which in turn increased their aggression.
"We focused on the motives of people who play electronic games and found players have a psychological need to come out on top when playing," said Dr Przybylski, according to the BBC.

Another study involved two groups playing the non-violent and vanilla versions of Half-Life 2 respectively. On some occasions, however, players were not given a tutorial on what to do.
No matter the type of game, violent or non-violent, the players became annoyed when finding it difficult to progress.
"This need to master the game was far more significant than whether the game contained violent material," added Dr. Przybylski.
