I'm about to pick up a Switch and probably as early as this weekend.  Buying a Switch was always in the works so it was eventually going to happen.  I just kept putting it off until that "right time."  As I type this post, my daughter is enjoy her last day in school as a field day so she'll be coming home with her final report card.  I promised her we'd get a Switch if she brings home all As for the last 9-week.  Going by previous trends in academic achievement, IT'S GOING TO HAPPEN.  So this is not a thread about "Do a buy a Switch or not?" because the answer is "DO."  But may I get any advice or suggestions on what I need to consider?  Here's what I've been thinking so far:

1) I'm eventually going to get a second docking station to we can easily... "switch" between two TYs.

2) I don't see us being very portable with the Switch unless we go on long trips so I still need to consider a carrying case.

3) How often do you need a second set of Joy Cons?

4) The games that mainly interest her are Smash, Arms, Pokemon Go Eevee, Mario Cart 8.

5) Games that I'm interested in are Zelda, Metroid, Mario, Shin Megami Tensei, JRPGs

6) SD Card advice

I'll flesh things out more as we discuss. Thanks, all.

2 docks for 2 TV's sounds good to me! Enjoy the new system. Have you ever thought about buying 2 Switch systems? - So you will both have access to one and won't have to share, as well as being able to play with each other more easily.

First of all congratulations for your excellent purchase. I have a lot of fun with the device, and I am sure you will as well.

As you buy the device for your daughter, but will play without a doubt yourself too I recommend creating different profiles and also recomment activating the excellent parental controls. You download a free app for your phone and connect it with your Switch, then you can regulate in the app stuff like play-time, age-restrictions on games, online and purchases in the eshop, while still be able to overwrite it with a pin-code. The app also allows you to see much better how much and what was played than the internal stats showed in the profile on the system itself.

1) Are additional docks available? If the price is OK and you plan to use multiple TVs, this might be a good idea.

2) Mobile usage is more awesome than you might think. You are on holiday breaks in hotel or something like this, then the ability to use the Switch is gold. A carrying case might be good if you fear for scratches or something. A cheap one will do though.

3) Depending on the games. I think stuff like Mario Kart you can play each with one Joy-Con, so two people can play out of the box. For Arms you need a double set of Joycons for each player. Or a Pro controller. Consider getting a Pro Controller, as this is pretty good. With an additional Pro Controller three people can play Mario Kart (Two each with a Joycon and one with the Pro-Controller) and two people can play Arms. If you still need more, you can go with more Joycons.

4) Seem like good choices to me. All for can be played with two people (Smash and Kart with more), all seem to me as adult kid friendly. You might consider Katamari Damacy for her and you, it seems like fun for both kids and adults alike and is one of the greatest games ever.

5) Get Zelda. Period. No one should not get Zelda. I hear Mario Odyssey is good too, so if you a fan of Jump&Runs you can probably do nothing wrong with it. Probably Mario also works for your daughter. There is no Metroid and Shin Megami Tensei yet released. If you like JRPGs, you should consider Octopath traveler, as long as you think the graphics are not too cheap. Also the old Final Fantasy titles are still great in my opinion. Xenoblade Chronicles 2 is also a pretty good choice, more real time and open world though. Also you should get Okami, not an JRPG, but always a good choice.

6) Each one available will not be enough if you start purchasing indies from the eshop. There are so many great indies. But you don't need to buy one right away. The Switch has internal memory that lasts you for one week or so, so use the time to look through the eshop, mark the titles you want on your wishlist and look how big they are. This should give you an idea how big an SD card you will need.

Eevee haters are horrible people! Probably even into something gross like polar bears or so *shiver*

I believe the Sandisk 256mb is both a good and reasonably priced atm. As for a 2nd set of joycons, i would recommend a pro controller over the joycons every time. Joycons are small, flimsy and unreliable. There are some good options for carry cases, depending on your requirements. For solely handheld there are some good cases for around £10/$10. If you want to carry everything there are a lot of specialised compartmentalised Switch carry cases but they are obviously a bit more expensive.

As far as games go, you can't go far wrong with a Mario/Zelda/Kart combo. Honourable mentions must go to Mario Tennis Aces and ARMS too, though it's not everyones' cup of tea. I noticed you mentioned Metroid. Unfortunately that has been delayed. It may be an idea to watch Nintendo at E3 to see if any updates are given. There are actually several JRPG's on the Switch. I've seen others recommend Octopath traveller, not got it myself but i would definitely recommend Xenoblade Chronicles 2. Anyway, enjoy your Switch! Although i'm pretty sure you will anyway.

This is what I use in my Switch, realistically if you buy one of these you won't have to ever worry about space unless you get 100 or so games digitally keep in mind that very few Switch games go over the 10GB mark most indie titles float around the 1GB point but that 400gb at time of linking is just 56sterling, that's cheaper than the 256GB card.

I'm sorry, i cannot endorse this statement.

Good to hear your daughter is doing well in school. I live in an area where most children are running around mimicking adults and it's for a lack of a better term, disgusting.

1. providing you don't mind the cost, a second dock is a really sweet idea.  I've been planning on getting a 2nd one eventually, myself.

2. I hardly ever go portable, but I have a case and think everyone should.  Along that line of thought, get a screen protector...sooner than later.  Hori makes a perfectly fine plastic one that has served me well, or there are gorilla glass types out there on the market as well.

3. joycon are not cheap.  That said, if the money is not a problem, grab a second pair.  Even if you don't have company that would necessitate a 2nd set, its nice to have an extra pair hanging on the docked Switch at full charge and at the ready.  Get a Pro controller first and foremost, imo.

4.  The sheer amount of quality games available for the Switch, whether at retail or in the e-shop, is staggering.  If I may, I'd highly recommend Diablo3 as an early purchase.  Its endless fun and the multiplayer aspect is great with friends and family.

5. Go with the largest sd card you can afford.  I wouldn't suggest anything under 128g.  Reasons being that there are so many great eshop titles to dl, and that there are many games that come physically that also require large downloads and they will eat up space rather quickly.  ie. Mortal Kombat 11, Bayonetta 1/2 (if you buy them together 1 is a dl code), NBA2k, Doom/Wolfenstein2 etc, etc.

Switch has so much going for it right now.  There's something for everyone.  Enjoy and have fun with the family!

(1) I picked up a second dock for this but almost never play on the second TV lol. But it's nice to have, if for nothing else, at least so I can travel and have a dock with me without disconnecting the one hooked up to my main TV.

(2) I play my Switch in handheld mode probably 85% of the time. Even at home. I may be an outlier here, but that's by far my favorite feature of it. Either way, if you do think you'll EVER take it out of the house, I think you should have a carrying case. I also keep all my game cards in my case, as well, so if not for travel, at least it's a good game card case.

(3) My kids like to play Mario Party with me, and most of the games I play for local multiplayer, you want a full modern gamepad for, so the second set of joy cons get their fair amount of use.

(4) All those games are solid, except maybe Arms. I find Arms overpriced, but if you can get it at a budget price it's a solid buy. You'll want a second set of joy cons if you want to play together though.

(5) Solid list, again. This Zelda is pretty much inarguably one of the top 5 best Zeldas, and many will consider it either the best or second best (other contenders are LttP, OoT, and MM). I've played through it multiple times. Metroid, of course nobody knows if it'll be good or not, but I mean, it probably will be.

(6) SD card advice = get the biggest one you're willing to put in it. There are enough free games and demos that you'll almost certainly fill a small SD card even if you otherwise buy nothing digitally. If you DO want to buy digitally, you'll run out of space FAST. I go about 50/50 for digital vs physical and I filled a 128GB SD card; recently swapped that one out and put in a 256GB one.
