Depends how you refer to the major arcana. If you mean just as their symbols or even including their occult meaning, they cover a lot of really general concepts and their interactions are fairly basic things, to the point that almost any story you can think of can be represented in a very general level through them. If you mean literally using the cards somewhere, I haven't seen them used anywhere other than general decoration or something.

It's easy to learn a lot of Tarot games. A lot of people don't really know (especially in English-speaking countries, which only commonly know the occult use of Tarot), but Tarot is just a set of configurations for playing card decks. There are tons of setups other than the standard French-suited 52-card deck, and they all have their own sets of games that can be played with them.
Just know that you don't want to use occult-designed tarot cards for playing games. They aren't designed to be ergonomic for that (most of the cards don't even have the number or suit printed in the corner), and are a pain to try to play with. You'll probably get a Tarot Nouveau deck (which uses the French suits you're familiar with from a standard 52-card deck, rather than the occult tarot decks that use Italian suits), but know that most of the ones you can find are French, so you'll have to get used to Valet, Chevalier, Dame, and Roi instead of Jack, Knight, Queen, and King.
Due to the trump card setup with Tarot, most Tarot games are trick-taking games (think whist), but there's a decent variety of games available to play.
Really, it's a fun change of pace. If you play card games with people who are used to picking up new card games, and show up with a playable tarot deck and explain the rules, it's just about as easy to get into as any 52-card game.
