The study by an international anti-bullying charity surveyed about 2,500 members aged between 12 and 25 on a virtual community.
The researchers found that 57 per cent of the young people surveyed had experienced bullying online when playing games.
They also found that 22 per cent of young people had stopped playing games as a result of online bullying.
Almost half of them claimed to have been threatened while playing an online game, and 38 per cent said they had been hacked within a game, 'BBC News' reported.
"It is this relationship that makes our findings all too pressing and real. Bullying within online gaming environments is a real issue," he said.
