So why do people buy a Switch 2?

I guess because my kids keep breaking the shoddy slide-on joycons, and the new magnetic ones are a much better design.

I don't have one, but I assume it's a better Switch. All the existing games work on it, some with enhanced versions (but probably load times are better anyway, right?), and there's new games that only run on the Switch 2. Switch 1 releases are likely to dry up over time.

For all the new Nintendo first-party games.

The best at the moment is DK Bananza but it’s nowhere near a Zelda game. The rest are updates and remaster of previous games.

There isn’t teal system seller at the moment
