Google’s Stadia has just been launched. It’s a streaming service, that allows you to play games through your internet connection without the need for a console.
This tends to need an extremely fast internet connection to get really smooth high quality sound and graphics. Without this, things will sometimes get blurry, sloshy and at times stuttery. The upside for some is that all the games are in one place with no need to update software or keep upgrading your computer/console.
