Hmm well that does make sense. Based on what you said, I guess this would be a great deal to take. Though I'm kind wondering why the price is so low compared to the others. Hopefully there's nothing wrong with it.
Edit: Found out why there are differences in price now. Apparently the Append version is a sort of bugfix to the original game along with some extra content on the disc. And it also won't run unless I buy the original version too. :S
