Could anyone tell me the main differences between the Nintendo Switch and Switch Lite? Is one better than the other? Also how do the games work...do you buy them, download them or can you do either? My daughter has autism and a mild ID so I'd prefer whichever will be easiest for her to use. She's 10 and this is the first time she has ever asked for anything specific for Christmas so i don't want it to be a disappointment if she can't use it.
