The top three are
1. Snowblind Aces by C.E.J. Pacian
2. The Snowman by Caio Miranda
3. TIGSaga by various (Terry, Kinten, Akhel, Xander, Haowan, Shinygerbil, and #tigIRC)
I plan to put up reviews for these three games (and maybe a few others from the competition) over the next few days.

Nice one – looking forward to the reviews!
