Yeah, in TOS S1 A Taste of Armageddon the Organians stopped an entire Intergalactic war between the Klingons and the Federation.
In ENT S4 Observer Effect, we have two Organians who have observed many a corporeal life form die to a silicon based virus just to see how they another crew members react.
In TNG we have the Q, which all seem to enjoy doing things to lesser beings,; and even though gynon has stated some of the Q are even respectable, TNG had never really shown us such a Q.
TNG S3 The Survivors, also gave us yet another Godlike race that referred to itself as a Douwd, who in a fit of blind rage instantly wiped out an entire space fairing corporeal species (the Husnak) wherever they in the galaxy; and also was willing to torture and drive Deanna Troi insane lest she discover that fact from his mind; and the only comment Jean-Luc Picard ultimately had on that situation was that, ".. He should be left alone."
So yeah, now with SNW, we discover that the Metrons are yet another Godlike race who enjoy toying with and experimenting on corporeal species. The sad thing is, showing them to be like this allows TOS S1 Arena to actually make more sense, as it didn't really track that the Gorn themselves could create such a perfect illusion of a Starfleet Commodore, that not only spoke with Kirk live just before Kirk being down to Cestus III, and also managed to keep the destruction of the entire base hidden until Kirk actually beamed down.
(IE - are we supposed to believe that Kirk & Co never scanned the planet on approach, or that in setting up to beam down, the transporter officer didn't notice the burned-out buildings that probably should have shown up as he's preparing to beam them down?)
