Which is the worst thing for your 17-year-old to do? Drink beer? Smoke pot? Watch porn? Or play Grand Theft Auto? While smoking marijuana was deemed the worst activity, GTA finished second in an online poll of 1650 people by What They Play, a website that reviews games from parents' perspective.
Pot smoking was listed by 50% of respondents as the thing they would be most concerned about their 17-year-old doing during a sleepover at a friend's house.
GTA came next on the list, with 19%, followed by watching porn (17%) and drinking beer (14%).
It's not a scientific survey, but it does give a provocative insight into attitudes about video games.
The survey is skewed by the particular demographic of visitors to What They Play.
About 86% of them identify themselves as parents looking for information on which games to buy their children, Tom Byron, vice-president of marketing for What They Like, the San Francisco company that runs What They Play, said.
The rest are grandparents, aunts or uncles.
Most are in their mid-30s to mid-40s.
The site conducts polls to find out what parents are thinking so its editorial staff can write content to address their concerns.
In April, several weeks before the launch of Grand Theft Auto IV, the site put up a poll asking what parents would find most offensive in a game: a severed human head, a man and a woman having sex, multiple uses of the F word or two men kissing.
The No 1 answer was sex, which accounted for 37% of the 1266 votes cast.
Men kissing came in second with 27%, followed by the severed head with 25% and the F word with 9%.
What They Like used the results to write one of the site's most popular articles, "Grand Theft Auto IV: 11 Things Parents Should Know."
"We have a motto here," Mr Byron said.
