Do I have to be careful if I want to play Super Mario Odyssey on the Switch lite?

I want to buy Super Mario Odyssey on ebay for my Nintendo Switch lite. I just don't know if the Super Mario Odyssey disc is compatible with the Switch lite?

Can play everything that has appeared and will appear on the Switch, the Switch Lite is exactly the same as the normal Switch, only without TV mode

No, that is wrong. You can play all games that work in handheld mode and that is not all.

So you should phrase it differently because it is important to know whether you have additional Joy cons or a Pro Controller. If this is not the case, you can't play all games

It is just a game series which also requires a controller, that is the labo series, but would run if he wanted it

No for some games he would need additional joy cons like e.g. Just dance.

All Nintendo Switch Games can also be played with the Lite. Only some (e.g. Super Mario Party) require their own Joy-Con controller
