Just look at the sales for Xbox One games on this site. I figure that on a sales website, you would be able to easily access sales numbers.
A quick Google search outside of this website and surely you will find that platformers, for the most part, are not usually big on Xbox consoles. Better yet, just look at the sales on this website.
I would not call those exception to the rule. The xbox has had almost nothing of worthwhile exclusive content, they where hungry and that's all they had.
It takes genuine talent to see greatness in yourself despite your absence of genuine talent.
