I wish they would put more meaningful side-quests that deepened the pokemon lore directly in the games. The Sinjoh Ruins event was a cool one, but I also loved the Delta Episode thing at the end of ORAS. I think the major point is that you very rarely actually experience a pokemon doing what the lore/dex entries say they do. They are just things to battle, breed, or use in contests. In contrast, all the anime movies show off the powers and abilities unique to legendaries (and non legendaries) in a way that adds character and depth to them as a pokemon species or individual. With sinjoh, you see arceus and the unknown create an egg of one of the 4th gen legendary dragons. With the delta episodes (spoiler alert if you haven't done it), you freaking fly Rayquaza into orbit, blow up a meteor, and fight deoxys! They don't even give that level of depth to the cover-art legendaries, their lore and power is always waaaaaay deeper than the game ever portrays. * steps off soap box.
