My 2 cents worth as a huge gamer.
Firstly nobody has really mentioned the new switch version that was released week or so ago. So you have the switch lite, switch original and switch oled. The main/proper switch that everyone has been talking about is the original. The switch oled that was recently released and is about £60 more, basically just has a better screen so please discount this. Your kids wouldn't be able to tell the difference at their age, I'd put money on it.
As others have said, the red and blue (or grey depending on if you buy the blue and red 'Neon' version or grey version) bits at the edge of the screen are called joy cons and are removable. You can either:
- Keep these on the screen and use them both for the one player using the screen.
- Detach them and use both for one person and have great fun pretending you are throwing something when you flick a joy con in the air.
- Detach them and let 2 people have one each as their controller. This is why if you buy an extra pair of joy cons 4 people in total can play. You can do this on the unit itself, or the TV I believe.
Personally I think if you can afford to get the original switch not the switch lite each, I would do. My reasoning for this are....
- If each child has a friend round they could all play 2 player with their own console.
- A lot of the best games on the switch are one player games, or best as one player.
- I've never known any 2 siblings to agree on anything, let alone 3 so less fights about which game to play.
- It is so much fun swinging the joy cons around like you are throwing a hat. You wouldn't get that with a lite as you can't Detach the controllers.
- If any of them don't like them or maybe the older one out grows it, it would be easier to sell it on and get decent money for it compared to the lite (I watch prices and sales and lites take a lot longer to sell on ebay than originals).
Right onto game recommendations...
Mario kart for the whole family
Mario party for the whole family to look silly and have a laugh
Mario odyssey great one player game
Mario bros u deluxe/super mario 3d great classic platform one player (no I'm not on commission by the way!)
Donkey Kong another one player platformer.
Minecraft/dragon quest builders one player mining/creating game.
Starlink battle for atlas which is a kind of explorer game that you use physical toys with. You get a starter pack with a rocket, a pilot and 2 weapons and then you can buy different pilots, weapons etc as add ons for pocket money prices.
Warioware family game with lots of silly mini games.
Colours live is expensive but great for kids, it comes with a special pen that you use on the screen and you can draw and colour. My nephews love it.
Any games you don't like you can take into cex or game and in both places either get cash for them or store credit towards new games.
Finally as to where you buy your consoles from...
I've had 4 faulty switch consoles so have had to do a lot of returns with varying degrees of ease. From my experiences I would definitely recommend buying from Sainsbury, Tesco or Argos. They all accept your word that the item is faulty without having to take it away for testing. The bonus is you get nectar or club card points with the purchases and no hard sell on extended warranties.
Obviously I hope you won't get a faulty console, but if you do I don't want you coming into an argument just to get a working item. Game will do nothing if they cannot see the fault themselves, smyths want a day or 2 with the item to check it out etc etc so with 3 kids I'm sure you don't want the hassle.
Hopefully this all helps.
