Microsoft Corp. said on Friday it acquired the rights to the "High Heat" baseball video game franchise from bankrupt software publisher 3DO Co. The company did not immediately disclose the purchase price. 3DO's assets were sold at a bankruptcy auction in San Francisco on Thursday. When the company filed for Chapter 11 bankruptcy protection on May 28, it said it would try to sell its assets. Microsoft already has its own baseball game, "Inside Pitch," for its Xbox but game critics have long considered 3DO's "High Heat" as the best among numerous competitors.
