>Pokemon World Tournemant>Like every legendary that wasn't in HG/SS>Both Gen 5 Games have places of the region you cant even explore until Post-Game>WhiteTree Hollow/Black Tower DungeonsEmerald just had the first Frontier, and even if you personally liked it more than the others, it hardly counts as a Post Game when every game that followed not only had a Battle Facility, but some kind of extended story/New locations to explore on top of it.
Hell, even Gen 6 had the Looker quests, and while people say X/Y had a very short Post-Game, nobody can deny that those quests were some of the best quests in the entire franchise.
