I'll tell you what should, but won't be the best selling exclusive game. (It will have more depth and content than Watch Dogs, Titanfall, and Destiny combined minus DLC.)

Oh hell yeah. Game of the gen!

Nothing SHOULD be the best-selling exclusive. While Xenoblade Chronicles X may become YOUR favourite game of the gen, it might not be mine. A PS4/XB1 or another Wii U exclusive might be better.

Well, there has to be one right?
