In Pokémon games the depth is technically endless because you can always catch and train Pokémon. But somehow Pokémon X(or Y) offers so much more. The whole Pokémon series had a couple of things like catch, battle, trade, and train. A couple of games had some gimmicks such as walking with your Pokémon or making movies but Pokémon X is very interactive. The new Pokemon-amie(means my friend in French) feature lets you PLAY WITH YOUR POKEMON! That's right Pokémon just turned into Nintendogs! You can play, feed, and pet your Pokémon. Not only that but in the past did Pokémon games seemed too complicated especially with EV training? Well it's so much simpler and faster now as the new "Super Training" let's you EV train your Pokémon with in 45 minutes to 1 hour rather than a whole day to train 1 or 2 Pokémon. Also did some Pokémon seem like they can do better? Well you can! The new Mega Evolution( temporary Pokémon evolution)allows you to have a new strategy in battling, as Pokémon can become stronger by temporarily evolving a step further! Pokémon like Charizard, Blastoise, Venusaur, Mewtwo, Absol, Gengar, Mawile, and so much more! The last thing left for depth is the new fairy type. Remember how Dragon types were completely overpowered? NOT ANYMORE! The new fairy type has a complete advantage over Dragon types and some old Pokémon has been re-classified as a fairy type like Marill, Mawile, Jigglypuff, Ralts, etc. So now if Dialga uses Roar of Time on a Jigglypuff then it'll say "Has no effect". I lied this is the last thing, the new Internet system is so much easier and convenient. Remember when you had to go to the Pokémon Center to trade, go through GTS, and battle online. Well it's a lot easier since you can press a button on the bottom screen and there you go you are at GTS, or battling/trading with a friend.
