There are a lot of games on this list, ranging from recent games to old classics.  The number jump around a bit, depending on the popularity of the game, and the market availible for it when it was released.  (and older game may have been intially popular, but sales slowed soon as it got replaced, etc.)

It’s an interesting list, and it goes on, and on, and on.
