Protips: If Bethesda ever released sales figures for Skyrim, we'd know about it. We'd have news articles everywhere pointing to a press release straight from the horse's mouth. Steam doesn't release sales figures, so the numbers would have to come from them. Any web site spewing statistics without referencing a source is flat-out making shit up, period. They're exploiting the desire for such information, preying on the gullibility of the average person who would take internet "facts" at face value.
