If you are planning on getting HeartGold/SoulSilver, what are you planning on doing differently? Pertaining to what you've previously done in Gold/Silver/Crystal, of course.
I'm going to keep my starter, but I'm planning on choosing different poke'mon for my team. Probably a Hoothoot, and probably not a Geodude this time.
Also, if they're still in there, I plan on getting more special Poke'balls.
When I first played through Gold I picked Totodile and named my rival "????". This time I will be buying SoulSilver, starting with Cyndaquil and naming my rival "Silver".
