One small feature that is a first for the Pokemon Industry found within the 7th Generation Games is the variety of Poke Balls Non-Playable Characters (NPCs) have caught their Pokemon in. In every Generation of Pokemon beforehand, it was either shown or implied that all of your opponent's Pokemon were caught in a regular old Poke Ball. This old concept is very unrealistic, and this change, though not extremely important, gives the games a little more substance. It's the small things that count in any good video game.
