Hmm
I played Runescape so I was curious about this when I read the review (yea, I actually read reviews). I can say it sounds nothing like a runescape song, only it uses one or 2 of the same sounds.
Well after hearing "SMB2: Credits Theme" this one isnt' quite as clear or original. I also see less effort. It's stil nice, the steady drums. This wasn't what I expected to hear underclassical though.
And it tells a story, I like the idea. It just needs a little bit of edditing to be perfect.
