Needham’s Turbine Inc., which makes the online video games Dungeons and Dragons and The Lord of the Rings, has cut its workforce as part of a restructuring at its parent company, Warner Bros. Interactive Entertainment.

“As part of the continual review of our business operations and fluctuating market conditions, we have had to make reductions in our Turbine workforce,” said Remi Sklar, spokeswoman for Warner Bros. Entertainment Group, in an e-mail. She would not provide additional details, including how many layoffs there were.
