premise: Wings of Glory is a World War I combat flight simulator video game for MS-DOS, developed by Origin Systems and published by Electronic Arts in 1994. The game uses Origin's RealSpace engine, which was first used in their earlier flight simulator "Strike Commander".
hypothesis: This video game uses the same engine as "Strike Commander" did.
reason: The text says that the Origin's RealSpace engine was used in both "Strike Commander" and "Wings of Glory." The way the text is written it may be hard for the model to recognize that it used in both.
