That's cool! Like playing classic Doom inside Doom 3. Is there a list of games that let you play older versions from within?
The whole original Maniac Mansion game can be played on a
computer resembling a Commodore 64 inside the Day of the Tentacle
game; this practice has since been repeated by other game
developers, but at the time of Day of the Tentacle's release, it
was unprecedented.
[1] https://en.wikipedia.org/wiki/Day_of_the_TentacleTried to find a TVTropes for this kind of thing, but couldn't. Surprised, seems like there'd be one.
The purest form of this specific thing is more like having an entire episode of MASH play on a TV in the background during an episode of Trapper, MD.
In the game there is a computer, which if you interact with it, allows you to play the entire original Maniac Mansion.
I wish more games did this.

I guess it sort-of doesn't really count, since the "games within the game" are essential parts of the game itself.
