While playing other people's games my team and I have been surprised at how many entries are only available as a Windows binary. I realize the vast majority of PC gamers are on Windows, but this is my third Ludum Dare and so far no one contributing to any game I've worked on has been on Windows (been a mix of Linux and Mac). Is there any info available on what percentage of LD participants use which OS? Web builds have gotten so good on so many engines I'm kind of surprised it's not the standard for game jams at this point.
