With just shows in general, I have a fair amount. Don't know the exact amount of cartoons, but I got a 1TB external drive almost full of them, a single live actions show from the 90s, a single live action movie, a few animated films, and a whole comic set. As for games, I don't count by size, nor do I know how many since they're not stored on a drive. I specifically got a 2TB external drive (both drives Seagate) for if I ever find more shows/whatever I wanna collect, but I have yet to find something I desperately want.

That, and I still need to use it to back up files so I can switch operating systems on my desktop.

Edit:

No idea how much music I've downloaded from yt using things like NewPipe, but I got a good amount. I'd assume this counts as piracy too, since I'm certain the people in charge of the music industry don't like you being able to do that.
