Oh no... Mother 3...

So Mother 3 sparked my curiosity randomly. 
It started with checking out some old Earthbound reviews. Then with digging around for anything Earthbound related. Then after I woke up from my blackout, I found myself listening to the entire Mother 3 soundtrack. 
THEN there was a Gamebaz page open in my browser with a listing for the Mother 3 GBM for almost a thousand dollars.
And oh GOd there are 2 up on ebay for about 600 less... What the hell.. 

Why do I do this to myself? I'm going to have to play this. I'd prefer to do so legitimately, but I am so enthralled...
