Yeah, I bought SimCity DS and found that it had an unlock code for the Washington Monument (a GameStop Exclusive!).
I figured that there were more and searched the web. I found a list, but it was missing one of the monuments (#12). Being the kind of person who can’t stand a missing bit of information, I went looking. I finally found it, but it took some work because none of the lists had the number next to them. So I compiled a complete list to share with anyone else who gets SimCity DS.
