Did your lessons also include important historical events? Afterall, history is often created through changes in society.
XY has in contrast to ORAS just a lot more atmosphere to it. All the Routes look particularly beautiful and you have caves like Glittering and Reflexion Cave, who have their own unique gimmicks that make them stand out. You also have trainer customization and every Pokemon obtained in XY has the Kalos symbol, as opposed to in ORAS where Pokemon just have this ugly Poke Ball symbol, that is also used for Pokemon transfered by Pokebank from a previous generation.
Also, how far are you in AS right now?
