There are hints in Wing Commander series and some consistencies in Crusader that would indicate the two series are actually in the same universe, though separated by several hundreds of years. Most notably: WEC, the "evil" corporation in Crusader, is mentioned in Wing Commander's historical fluff. There's no references to WC's events in Crusader, though, but that would only solidify the assumption that they're in the same universe rather than being an easter egg.
