But gaming's active, bidirectional nature makes it different from traditional movie and music streaming. It's also different from Twitch-like game broadcasts, which is why I prefer "cloud gaming." 

That term also differentiates it from in-home streaming -- served up by the original Steam Link,  HP's Omen Game Stream, AMD Link mobile and a lot of others -- where you run games off a local system to play on less powerful devices but those devices are still on the same network. They're also different from online multiplayer games such as Fortnite, which run entirely in the cloud but still perform most of the processing on your device.
