This feature is really one of my favorites in HG/SS. Even if it may be pointless, having the Pokemon walk around with me was very fun, and it was always nice when the Pokemon have an accessory, or they show affection towards you, etc. To me, it felt like we had a greater bond, even though it may just be pixels on a screen. I thought of my pokemon in HG and SS as more of my buddies than in previous games, as I could see its reactions during various times. Overall, great feature, and I wish it came back in Gen V.
