>>53271667I like Kalos Pokedex distribution much more. There's Pokemon from every generation in each sub-region (central, coastline, mountain). The maps feel distinct, because you don't see the same Pokemon or encounter types too many times. People make fun of that IGN ORAS review guy with the 7.8/10, but there's some truth in it.
ORAS also removed player avatars and boutiques, which is lame because contest coordination is a thing.
