CalamityRanger: I do wish they kept the 'your Pokemon walk around with you' option from HG\SS.
Roberttitus: Wait... what?
The first Pokemon in your party actually was animated walking behind you when in most areas of the game in HeartGold/SoulSilver. The first Pokemon in your party is still considered being "walked" as far as raising happiness goes, but it's not animated. Walking a Metagross or some of the Legendaries was pretty fun.
Btw, if you pick up HG/SS at some point, you can collect a ton of Legendaries from them. Also, Platinum had all the legendaries from Diamond and Pearl plus a new one, so if you get a pre HG/SS Gen IV game get Platinum.
Pokemon is huge, if you get stuck Bulbapedia (which has slow ass servers even during the best of times and is hammered right now) has a lot of great info as well as Serbeii.

CalamityRanger: In HG\SS the top pokemon on your list would walk around on the map with you. I liked it a lot and would often turn around and click on them to see what it says. Now I can't say for sure as I'm not far at all in Black but from screenshots it doesn't seem like they kept that in.
Sometimes they found some pretty damned good items while walking too.
