I found this link earlier

It is the 100 greatest pop culture icons. What is wierd though is that the only video games character in the list is lara croft. No Mario, no Pacman, no Space invaders, not even Sonic the hedgehog (all of which IMO are bigger in pop culture than Lara Croft).
Fair enough Videogames are not the biggest thing ever but I think a list of 100 popular culture icons should at least feature 3 VG characters.
