Nintendo Switch Online launches today, and no doubt many of you will already have subscribed and gotten stuck into all that lovely cloud-saving, online goodness.

However, perhaps the biggest draw at this moment in time is the fact that the service comes with a bunch of NES games which can be played over the web with other Switch owners. It's the future!

How does this voodoo work? What's performance like? What's low-latency mode when it's at home? Alex (with some help from Daz) is here to answer all of these questions and more in the above video. Enjoy!
