Buggy to the point of being broken and rough around the edges in general.
Much more playable, is the last one that feels 'dated' (although still great).
This one feels like the first very polished entry in the series. The bugs are minimal, and the mechanics are made somewhat more sane.

Very modern feeling, with updated mechanics and mega evolutions. X/Y feels very railroaded, and kalos lacks the same exploratory feel as the previous region. The new pokemon's designs had a few great hits, but many misses.
doodie feces, like a railroad leading to a landfill.
super slow and the mans who your supposed to care about *BLOCK UR PATH* every 10 seconds. Cool mons. Tapu cancer.
