Their list is a bit too short, I think, but they're looking at games which affected the world in general, not just gamers (even casual gamers). Doom has gotten a lot of mention over the years, on the news and other such places. Guitar Hero and Dance Dance Revolution are amazingly popular among people who otherwise don't play any computer/console games. WoW is amazingly popular and everyone's heard of it. I'd bet a lot of WoW players don't even know there was an old RTS Warcraft game...
Games which changed the game industry is an entirely different subject.
