Why did you abandon a (I'm assuming) nearly complete game?
Then when I replaced the graphics I continously added new features as well and a popular video game musician (Chris Hülsbeck) joined the project. Now with so much talent working for the project I felt like the gamedesign wasn't a good match for it anymore, so I basically started over (I thought about this for a month or two, then finally throw away all source code and restarted without realizing that I have basically threw a nearly finished game away). This sounds pretty dumb in retrospective, but back then I just didn't saw it.
I've said approximately this sentence so, so many times in the past year.
