Nintendo SwitchThe Nintendo Switch was on sale for less than three months when the production line ran dry - which is evidence in itself of just how much gamers are loving this thing.
With an innovative design and a host of multiplayer options, the Switch is breaking new ground in the gaming world, and has helped Nintendo to steal a march on its competitors after spending years in the shadows.
So - what's the fuss?
Nintendo have succeeded where many of its competitors have failed, in creating a genuinely fresh and original gaming system, replete with gimmicks not seen in any others before it.
The first and most notable of them is that it can be used "on the go". You can either hook it up the dock and a widescreen television or lift it from its holster and use it as a tablet. All games theoretically support both uses, although in practice some will obviously be better suited to one more than the other.
If you do choose to go portable, battery life is estimated at around three or four hours, which doesn't seem like a lot at first glance - but bear in mind that this thing has a high resolution 720 screen to prop up.
The Switch's controllers can either be used as nunchuks, or you can attach them to the sides of the console and use them as a traditional joy-pad, with the screen in the middle.
If Nintendo have been generous on the cost of the console itself - just £279.99 - the add-on accessories are altogether more pricey (and they also tend to have that annoying habit of ensuring that only their own official merchadise is compatible with the main hardware).
Securing fresh titles for its product range has often proved a stumbling block for Nintendo, but the early success of the Switch has won some developers round.
IGN, for instance, will be releasing WWE's 2K20 in 2020 on the Switch. It has been released on most other platforms and soon you will be able to enjoy it on Switch too.
Multiplayer sports-titles like FIFA, among the most popular for users of the PlayStation and Xbox, are on the Switch as well - but there will inevitably be those say the full range of their potential cannot be explored without a bigger engine.
Elsewhere, the usual Nintendo suspects like Mario and Zelda are all signed up - and the Switch will be the only console on which you can play them, giving it a big edge over its competitors, whose exclusive title ranges boast far fewer options.
As noted, the console itself is relatively cheap compared to other consoles on the market, but the catch is that games are super expensive at £60 a pop, and the best of them - Zelda, for instance - don't offer much in way of multiplayer experience.
The gimmick itself is enough of a novelty that hardcore gamers will give it a second look - although it is probably a better approach to share one with a friend instead of buying your own because it will wear off eventually.
