Probably a slower diffusion of ironworking into Western Europe and probably also a different tech trajectory for the EAstern Mediterranean, with indian and Mesopotamian civilisation having greater influence in Asia Minor. Of course Greece and Pheonicia are both gone from that world, too.
Indeed, especially as that dark age would encompass the middle-east and India.Wrong Dark Age.
