By night, he is an expert gamer for the online information source About.com, battling Imperial stormtroopers. He spends evenings, weekends and even vacations playing games and writing reviews and articles for the Web site.

Not just any games, but the kind played on boards with dice.

Arneson, 37, acknowledges that his dual roles sometimes earn him a "nerd" label. As chief policy director for Senate Republicans, Arneson works behind the scenes crafting legislation.

But, he says, "I'm completely comfortable with my geekiness. The bottom line is, it's fun."

Arneson, a graduate of Temple University, said that he always enjoyed playing board games growing up in Lancaster County but that it wasn't until May 1999 that he turned it into a second job.

He and his wife had already been writing for About.com, reviewing bed-and-breakfasts, when he saw a posting for the board-game opening.

Now, Arneson attends conferences and events across Pennsylvania and in surrounding states to try new games, meet publishers, and banter with fellow enthusiasts.

He estimates he plays games at least 100 days a year and posts his analyses on About.com at least once a week.

In the age of computer and video games, Arneson's love of board games may seem like a throwback to a bygone era. He disagrees.

"People spend so much time at work interacting with computers and machines that some quality, low-tech entertainment often hits the sweet spot when they get home," he said.

The Internet has helped boost board-game sales by making it easier for small and mid-size publishers to find an audience, Arneson said. And there is still a market for longtime favorites.

Board-game sales in 2007 totaled $1.07 billion, up from $1.01 billion in 2005, said Anita Frazier, a toy and game analyst with NPD Group, an independent research firm in Port Washington, N.Y.

"The big, classic, mass-market games still represent a huge dollar value," said John Kaufeld, spokesman for the Game Manufacturers Association. "Monopoly is not going away any time soon."

Arneson reviews everything from Monopoly's latest offering to Elemento, a chemistry-theme card game, and the latest in the popular board-game series that started with Settlers of Catan, in which players compete to build roads and cities on an island.

He has also offered his thoughts on Hannah Montana Girl Talk.

His Senate work often conflicts with the annual, invitation-only Gathering of Friends board-game event in Ohio. (Yes, there is such a thing.)

That means Arneson can attend only a few days of the 10-day gaming marathon. But when there, he makes the most of his time.

"I go play games and only break for eating and sleeping until it's time to leave," he said.

Then there are those rare times that he can combine his two loves. This summer, he and another political staffer will present a seminar on political games at the World Boardgaming Championships in Lancaster.
