A generally safe, predictable and agreeable list for the most part. The only things I really disagree with are when they choose weaker entries in a franchise at the expense of some of the stronger ones. Total War, Diablo and Starcraft for example. Although given that accessibility is a key factor in their rankings, it's understandable.
As far as what I'd personally change, I'd cut out a few of the redundant choices to add some slightly different experiences. For example, we don't really need both Fallout 3 and New Vegas in there, if you play the latter then the only thing you miss of the former is the story.
I'd have liked to have seen:
Homeworld - No other RTS has done 3d space strategy anything like it
Life Is Strange - So far it seems to be the best implementation of meaningful choice and consequence in a game to date.
Jedi Knight: Outcast - Really surprised it didn't make the list, I thought it was generally considered one of the best Star Wars games (alongside KotoR)
Age of Empires 2 - Again, a surprising omission given that it's one of the most popular and definitive RTS games ever
