In my opinion, the end credits in Generation V were weak compared to the other generations. Especially after we got a simple 'travelling back home' end credits for the Sinnoh games, and some sprite montage in the Johto games, of Generation IV.
I want to see some sort of interactive end credits, sort of like the beginning of LittleBigPlanet games, or the more favourable option, have graphics relating to the player's journey pan across the screen. I understand how putting Pokémon in there can be difficult, but it should be easy when it is just the player character with a stand off against the Gym Leaders, Elite 4, and Champion, and their Pokémon. Maybe even some for the Rivals and the Villainous Team.
What do you want to see in the End Credits?
