I imagine that those buying the #Switch2 at launch are pretty hardcore gamer-sorts. As such, they've likely already played, or have decided against playing many of those third party games that hit the Switch 2.
Throw in the fact that many of these games are priced significantly more expensive than they would be on other platforms that they likely also own (hardcore gamers), and the fact that many of the games have been out for years; is it any wonder this has been the case through the first few weeks?

It was the biggest console launch of all time, but was Nintendo Switch 2 a success for third-parties?
