Fallout 4 isn’t just causing a wave of “sick” days across the planet. The excellent open-world role-playing game is also eating into the time people spend on … other habits.

Pornhub, one of the world’s most popular adult video sites, told GamesBeat that it saw a 10 percent drop in traffic among gamers after Fallout 4 came out earlier this week. On November 10, traffic started to drop at around 5 a.m. after most people finished downloading and installing the game. That decrease from normal patterns continued until around 3 p.m. Gamers then seemed to disappear again beginning at 6 p.m.

“We can’t say we’re too surprised with what happened to our traffic during peak gaming hours,” Pornhub vice president Corey Price told GamesBeat. “Based on the data, it looks like a huge surge of people decided to indulge in some wasteland wandering by taking the day off of work and school to play, while the rest of the world had to wade through what we assume were the longest hours of work ever in anticipation of some alone time with their consoles.”

The release of Fallout 4 is easily one of the biggest of the year. Publisher Bethesda released some early sales data today, and it confirmed that it has already shipped 12 million copies of the game. The postapocalyptic adventure is also one of the most played PC games ever, according to data from the digital-distribution platform Steam. At its peak, more than 400,000 people were all playing Fallout 4 at the same time, and that number regularly rests around 350,000.

You gotta think that a few of those Fallout fans also spend some time on Pornhub … or maybe you don’t have to think about that.

But despite losing some traffic, Pornhub understands.

“As huge fans of the game, we can’t say we blame anyone for swapping Pornhub time for some Pip-Boy surfing instead,” said Price. “We would have done the same.”

Oh, and it’s not like the gamers didn’t return. Pornhub use among gamers skyrocketed starting at around 11 p.m. on November 10 — I guess the vault dwellers needed a break from The Commonwealth.
