7. Doom 3
Units Sold: 3.5 million
Metacritic Score: 87.5
The reboot of the Doom franchise released in 2004, Doom 3 proved to be a huge success. It is considered id Software’s most popular release and uses horror elements to great effect. Much like its prequels, Doom does an over the top shooter that somehow feels just right in the world they’ve created.
