Quoted from Mike_J:

I am hoping there is half left. I think most folks would be doing cartwheels if they could get half of their money back.

Quoted from Noahs_Arcade:

I posted this in the other thread, but it applies equally here.
From skitb's website:
"We're not ones to ever leave something at a simple answer, though, so we thought it would be interesting to show how it was made in the most step-by-step way possible without seeming like a tutorial. That being said, if you have any questions about it, go ahead and use our contact form and ask. I do wish we would have documented everything in a more complete fashion, but, you know, hindsight and all that. I'll do my best to keep a tally of money and time spent on the project as we go along, as well, just for information's sake."
From a bookkeeping standpoint, that scares me
