there is no one list to compare systems with.
depending on the situation different lists are important. For some people the list is why I should by a ps3 or xbox360 what will have more of what I want. In many cases the person with do all their gaming there. In many more cases they won't. In some cases listing all the games they play make sense in other cases listing only the games you can't already play make sense.
Listing all games a system can play when you can play 80% of the lirbrary or more elsewhere makes a list much longer than it needs to be.
Assuming everyone has a pc that they prefer playing games on (or any other platform games are also on and thus dismissing them) listing only the complete exclusives only helps those who have gaming pc or other systems.
recently there was the list from 2010 on. That list was trying to make the point of how much support a system had in it's later years or after motion controls. I think that list was a little to restrictive to make the point seem stronger. I would have included digital as well as at listing the console exclusives, labeling them such. Getting a game on pc/xbox is still getting the game and that is still supporting the system
