 I honestly never got why people so adore that mission. So much of it was just boring padding to me.

Well if I went back to it now, I have a feeling it wouldn't have the same effect on me as when I first played it. For its time, I thought it was amazing. People love it because they have fond memories of it like I do. :P

Ah, comprendo. Thanks.
