BioWare's space opera paved the way for a new generation of RPGs and characters that would stick with us for the long haul. The tale of Commander Shepard may have drawn to a close with Mass Effect 3's ending to the trilogy, but if the rabid community and die-hard fans are any indication, the industry will never be able to truly say goodbye to the Normandy and its colorful crew members.
