There are occasionally threads about top-selling franchise lists, which are difficult to put together.
Well, for the next person who tries to do it, you can put the Tom Clancy franchise down for 50 million units and then some. As far as I can tell, there are less than 15 videogame franchises in history to sell 50 million units.
The Tom Clancy series has gotten to the mark through a huge amount of consistently selling titles instead of fewer, mega-selling games like Gran Turismo and the Legend of Zelda. The top selling Tom Clancy game in the VGC database is the XBox version of the original Splinter Cell, with less than 3 million sold (and another~2.5M for the PS2 version), but the database lists over 65 different games, most with no data.

"[Our former customers] are unable to find software which they WANT to play."
"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
