Perhaps because of the free multiplayer beta offer, Steam's top 10 best selling games for the past week has Battlefield Bad Company 2 on top for the second week in a row. The upcoming shooter title from Digital Illusions is followed once again by BioWare's just released RPG Mass Effect 2 in second place with the Digital Deluxe version taking fourth place. In fact the original Mass Effect found itself in eight place on the list this week. Third place went to Modern Warfare 2 while the indie MMO game Global Agenda plants itself in the fifth position.
