Pokemon X and Y released over the weekend and it's pretty fantastic. It's also become easier and less time-consuming to raise Pokemon than in previous generations. The reason for that, according to Game Freak director Junichi Masuda, is that the smartphone generation simply can't devote as much time to raising Pokemon.
"Nowadays, we have the Internet, smartphones, and more, so I think the time spent playing games has decreased," Masuda told Famitsu magazine (via Siliconera). "For those reasons, we made it much easier to raise your Pokemon that will allow you to play smoother and more comfortably than before."
One way in which raising Pokemon has become easier is through simply catching new ones. Catching Pokemon will now reward XP, a change from previous iterations of the series. Another is through the idea of the game's Horde Encounters, which allow players to scoop up gobs of XP in a single battle.
