Take a look at this list on the Wikipedia: https://en.wikipedia.org/wiki/List_of_best-selling_video_game_franchises#
All of the games in the 300 million copies, all of the ones in 100 million copies, most of the ones in 50 million copies, and even a few in 20 million copies.

Awfully suspicious that most of them on are there under a vague company. Isn't it?

Vimm's Lair has been asked to remove many games from The Vault on behalf of Nintendo, Sega, Lego, and the ESA. While most of these games (and the hardware to play them) haven't been sold in decades, ultimately it's their prerogative so these games are now gone for good.
