I'm a big fan of the mystery dungeons, I like the whole quiz at the beginning and it deciding what Pokemon you'll be. But I've heard they've gotten rid of that and you just choose, which kinda sucks in my opinion.
Favourite Pokemon? pffft, thats crazy, I would be here all day.
'Finding every Pokemon is like count each sand grain on your favourite beach'
I don't know which Pokemon movie intro that's off, but the point is there's too many Pokemon for me to have a single favourite.
