I voted for,
Spacebase DF-9 - I enjoy sim games and anything related to space.
The White Birch - Art style and if it could give PC gamers a game similar to Journey I'd be happy. I've never played Journey or the other games from That Game Company as I don't own a PS3 (just not enough games of interest for me to consider it a worth while expense), but I think the PC needs more games like Journey, Flower, and Cloud.
Black Lake - The concept really intrigued me and I'm curious to see how the prototype will turn out.
Hack n' Slash - Seems like it could be an enjoyable comic take on an action adventure game that adds unique mechanics.
KAIJU PILEDRIVER - Seems like it could be a fun game to spend a bit of time in every now and then.
The Knockover - The pitch grabbed my interest, plus there isn't many games like it. Even though the prototype would have been a simple card based game it could pave the way to a more strategic game.
Cloud Prix - Seems like it could be a nice, fun, and simple racing game. I like Nitronic Rush and it seems like Cloud Prix could be another one to follow in the same vain.
The Flock - Seem liked an interesting game that would have been slower paced and interesting depending on the mechanics incorporated into it.
Autonomous - Concept seems intriguing.
Echelon - Seems like it could have been a every deep game with the player managing multiple things at once and trying to keep track of everything.
