I agree that would be nice, but I don't know if there is an easy way to list out all the finished projects of the year. It just seems like too big of a task with the volume of projects that have to be sifted through.
I would love to nominate Nephasth's two headed beast, but I couldn't figure out if it was officially "done", although it looked about there as of it's last updates in December. I know my SNES project early last year could fall under that same issue. I don't know if I ever declared it "done" even though it is and I have been playing on it for months.
