If you're wondering why Thimbleweed Park isn't anywhere to be seen in the IGF awards, it's because we didn't submit it. I have some issues with the IGF. The IGF doesn't do this, but I also won't submit to any awards that make you pay just to be considered (BAFTAs, DICE). Awards are basically cool-kid popularity contests and often have nothing to do with how good the game actually is. This is also true for movies and music. The academy award isn't the best movie, it's the best movie made by people academy voters think are cool or "in".
Update: apparently you do have to pay to be considered for the IGF awards... it's only $80, but still.
