BioWare's director of online development Fernando Melo presented the above player completion rates for Mass Effect, Mass Effect 2, Mass Effect 3, Dragon Age: Origins and Dragon Age 2 during a panel at GDC Europe. Mass Effect 2 topped the charts with 56 percent of players completing the entire game, followed by Mass Effect 3 with 42 percent, Dragon Age 2 with 41 percent, Mass Effect with 40 percent and finally Dragon Age: Origins at the lowest rate of 36 percent.

The spike in Mass Effect 2's completion can be attributed to Mass Effect 3's recent launch, when an influx of players were reminded of the game and attempted to finish it before that release, Melo said.
