I'm thinking of getting a Nintendo switch lite… Now my question is, can you play fortnite on the nintendo switch lite (the smaller version)?
Yes you can! Also got a Nintendo Switch Lite a few months ago. You just have to download Fortnite from Nintendo Eshop.
You can
Yes, because the Switch Lite accepts all Switch games that work in handheld mode, but I wouldn't recommend this to you because it is quite tiring if you regularly play with a Lite and you have other disadvantages as well.
Better buy a used switch with receipt on Ebay. But with PayPal and the option "Goods & Services" or by pickup.
You have more of that.
Just play good games
