Mmkay. I stand corrected. But still, my point is that most boys will shoot for the one that doesn't have Heart in its name. I may very well end up with both, but I'm going with SoulSilver first because I like Delibird, Ledyba, and Phanpy better than Gold's exclusives (although, Phanpy may be in HeartGold instead, as it was exclusive to Gold in the Japanese versions). I'll keep an eye out for that.
For those looking at SoulSilver for Lugia, change your mind! Get HeartGold and find Lugia at level 70 instead of 40! YOU WILL HAVE TO WORK HALF AS MUCH!! : ) )
