Most of America's most popular games have no love relationship at all.
Call of Duty, Gears of War, and Halo all three are American games...wait damn it your right in Halo you can kind of count the relationship between Master Chief and Cortana its a stretch but sort of and Gears has Dom looking for his dead wife. I guess its because Romance makes for a good story arc and can get people caring for the characters( Off-Topic: the alliteration in that makes it sound ridiculous when said out loud) and thus into the story.
