Why such a huge gap in quality between Playstation and Xbox exclusives?

Microsoft is only focused on games that sell which isn't always bad but shows that they are not creative in the slightest. It also keeps them from having new IP's and taking risks. Sony keeps the titles that sell well amd keep trying to make more every gen. That and when they try to make new IP's themselves they mostly fail.

Well, "only" in games that sell is an exaggeration.

Explain Microsofts lack of new IP's when they have more studios than Sony.
