To claim that graphics don't matter to games would be like claiming cinematography doesn't matter to movies. On the other hand, making a generalization that graphics are "60%" of all games would be just as silly as making a percentage claim for movies.
That 60% of Crytek's development resources are spent on graphics seems plausible, and it's working for them. But that's just their games. FTL, Binding of Isaac, Minecraft, or lots of other smaller games are almost certainly not spending 60% of their time on graphics, and most of what they do spend is more likely art direction than technology (The quote in the article did include art direction in "graphics"). That works for them too. "The Game" is a very broad term if you take that statement at face value. We should take it as a statement only about Crytek's games.
