I keep my "finished" games first. I put 20 hours into PuzzleQuest Chapter 1 and finished it, and finished all 180 levels in PixelCross. I will finish PicGrid tonight (finished over 50% yesterday) and I have about 25% to go in Glyphos. The rest are my currently-being played games. I will probably finish Yard Sale Sunnyville first. ChessQuest is awesome with 1200 puzzles to finish (I'm at puzzle 129). Been playing chess since I was 5 or so.
