I'm guessing all those people, spent all that time doing nothing but writing those books. Forget about eating, sleeping, having any leisure time, the things that normal people do. No, they just wrote and wrote and wrote, until they collapsed from exhaustion. And then a few hours later they started writing again, until they collapsed again from exhaustion. I think Eva is likely a normal person, who needs to do normal things, besides just working obsessively on a project till it's completed. Thus she can't churn out this game, as fast as those prodigies, with their obscenely abnormal workrates.
