Well if you count total then I guess you could say that Steam is the fourth largest platform out there. If you count total users I guess it would go Steam, Xbox 360, PS3. If you counted online purchases the rankings are probably either Xbox 360 or Steam, but probably Steam on top due to more expensive content. If you were counting online players at once then probably Live -> Steam -> PSN -> Wii.
