I pretty much use them constantly. They're useful for playing any shooters or anything with mouse look, they're great for RTS, city builders, point and click adventure, Factorio, etc. Currently I'm playing Dawn of War, Ground Control, 688i Hunter Killer and Fleet Command, which basically requires trackpads. I also play Stronghold Crusader, Warhammer Gladius, Company of Heroes, Warframe, WoW and other MMOs on it. I honestly don't know how people get by without them, they're extremely useful.

Even for emulators, they're great for binding all kinds of extra functions.

Using the right trackpad also means I can free up the right joystick for other stuff, and there's always enough other stuff I want to access regularly enough.
