I've just watched the list and in fact it's just the best sellers :! Just the Video Games that were the most sold in the world (if I'm not mistaken).
Wii Sports first ? Logical as it was a bundle with the WII ! So for me it doesn't count really... and it's the same for most of the list : the best sold ones aren't the best one...
You're right too : there is absolutely no Zelda in this list... very strange ! And about Phantasy Star it's logical this time as it's an old serie (I don't count PSO and PSU and other one online games) and the copies sold weren't so high... but what counts is only we know that it's the greatest serie of all time :! (or one of them !

).
