Am I alone in thinking that Chao take way too long to evolve in Sonic Adventure 2? I mean you need to be in the garden for several HOURS real-life time, and time spent doing stuff like collecting animals, rings, or Chaos Drives in other levels doesn't count. I don't want to spend ages in the Chao garden just waiting for Chao to evolve, and there's only so much you can do in the game until then. What do you think? Also, on a partially-unrelated note, what's the point of getting the Chao key as a character who's already unlocked Chao World?
