I have a niece in kindergarten, and she's the only one of her siblings to not have her own device to play games on. She really seems to enjoy playing games though, so I thought maybe I'd get her one for Christmas either this year or next year.
My first choice is a Nintendo Switch. This is the most obvious one because it's very popular, has a lot of kid-friendly Nintendo games, and is the cheapest out of all of them.
My second choice is a PS5. I'd have to wait until next year to get this for her, but it's supposed to have the best power and graphics, plus backwards compatibility with PS4 games.
My third choice is an Xbox Scarlett. Again, I'd have to wait until next year, but full backwards compatibility with Xbox 360 and Original Xbox, plus launching with Halo Infinite makes it seem attractive.
My least likely choices are PS4 and Xbox One. These are on their way out, as they will be replaced and made obsolete next year by PS5 and Xbox Scarlett. I don't wanna get her something that won't be contemporary anymore right after she gets it.
