And that little Earth on there is basically the symbol of the Mother series (well, in Smash Bros. anyways). Back a while ago, there was a post on EarthBound Central that showed that the earth is actually based off the famous picture of the Earth, Blue Marble, upside down: http://earthboundcentral.com/2010/08/the-world-is-mother/
Although they don't match exactly (the Mother version is just a bit more simplified) they still match up pretty well. So why am I talking about this? Well, before I knew about the whole Blue Marble thing, I thought that the Earth in the logo was deliberately made to have certain things in it. What things? Well, I'll show you.
This all started when I got too close to my TV while playing Brawl and started inspecting the little logo. Firstly, I saw an M on the Earth and I was all like "Oh cool, M for Mother!"
Looks an awful lot like an M, doesn't it? And then I saw something else, and you may have to keep an open mind for this, but I saw what looks like an alien's head, Giygas' (not his Mewtwo-like form) head to be specific.
Still don't see it? Here:
I admit that it might just be me seeing this, but for some reason it reminds me of Giygas. Let's compare:
Hmm, it actually looks more plausible than I thought it would side-by-side. Juxtaposing these pictures made me wonder; is the some insane weird chance that maybe that little "face" in the logo inspired Giygas' design? Probably not, but hey, this isn't Over Analyzations of EarthBound for nothing.
