Are game Actual Plays a Thing?
Actual Plays are definitely a thing. Which actual plays you enjoy will very much depend on which groups you like listening to, in general (not just playing a game). I can't stand Critical Role, for instance, but I enjoy the heck out of RPPR. If you're looking for specific games, just give a Google for the name and "actual play". For Four Against Darkness, I found a series on Youtube in a few seconds.
One Shot is another podcast to look at which has a lot of individual games and covers a lot of ground (though I didn't see that particular podcast in my Google).
