The reorganization, intended to eliminate poorly performing brands, includes closing Dynamix, the game development studio best known for the "Tribes" series of action games. Development of future "Tribes" titles and other ongoing Dynamix properties will be handled by Sierra's main office, according to a Vivendi statement.
Sierra Home, responsible for cooking, home design and publishing programs, will largely leave the software business to focus on print publications, Vivendi said.
The closing of Eugene, Ore.-based Dynamix will eliminate 97 jobs, according to the announcement, with another 148 positions to be cut at Sierra's main office in Bellevue, Wash.
"While any reorganization involving staff reductions is difficult, there is no doubt that this is the right thing to do for the business," Sierra President Michael Ryder said in the statement.
Vivendi laid off 39 people earlier this year as it trimmed Flipside.com, an online gaming subsidiary.
