Man, if people are just getting worked up over an overworld sprite...and little wind markings XD...this truly could be one of the best Pokemon games (and remake of any game). Hey, I love the changes, too. :)
It would be AWESOME if the starter's full-evo form followed you for all of the game! And since full-evo overworld sprites were seen in Platinum, I think that it'll be present in HG/SS. I really don't think Nintendo would be that cruel to only use such a nostalgic feature for a brief excursion in the game.
And I'm glad Nintendo has shown it can implement past, one-time features! These means that RSE-style Secret Bases can return for faster training! (I hope... :D) It is one of the features I'll sorely miss when I play Platinum... :() So far, 10/10 for HG/SS, and I hope the numerator increases on that fraction in the future! :P
Lastly, I REALLY hope Jimmy/Gold and Marina/Kris get awesome-looking redesigns. (I really don't want to have to name myself "Jimmy" in one of the potentially best Pokemon games of all time! (Yeah, I like to connect the game characters with the anime! Don't judge me! However, usually only the rival characters. If Jimmy/Gold looks exactly likes he does in the anime, it's gonna be the first time I'm forced to match the Player character to the anime :(. Which is why I'm (for the most part) happy that Brendan and Lucas are not named in the anime, and Ash does not look anything like Red's FireRed redesign!! :D)
P.S. We better be able to change Silver's name! (I don't know if this was in GSC as I have not played them)
Keep the awesome updates coming, Nintendo! Excellent work so far! :)
