Imo. The upgrade is not really worth it if you already own a switch. The OLED-screen is definitely an improvment of the older version, but that alone doesn't warrant paying 300 CHF (for me). As It doesn't feature new hardware in terms of the computing/graphics unit onboard

The game is not included in the upgrade. The upgrade console is already better..., better and bigger screen, better handheld stand, better battery. Cables can be connected/stowed better.
And slightly better wifi. It's a question of whether it's worth it. In retrospect, I'm happy with it
