I'm in

Also I got through the whole slaughter for the first time - the statistics pie really helped to keep motivation.
The most interesting theme I encountered was "cold". It's a simple suggestion which immediately brings pictures to my mind and is flexible to create a variety of themes and topics dependending on the angle you go at it. You can look at it from the survival standpoint, the thematics of coldrelated events like the often mentioned Christmas or the sheer feeling of being cold.
And as a bonus there never has been a similar theme for ludum dare. There were just a handful of similar suggestions like "ice" or "arctic" but all in all cold was unique, so I hope it get's a chance against the big and often repeated topics.
Speaking of! The big three I noticed:
If you suggested "something, something color!" - than I gave your suggestion a go ahead.
If you suggested "something, something time!" - than I slaughtered your suggestion.
If you suggested "something, something audio!" - than I slaughtered your suggestion.
Also there was the topic of an imaginative sport, which I came around after a while. My Topics where "Mechanical Monstrosities", "Fix Your Game" and... I honestly forgot the third one.
Oh well, what was your favorite suggestion, that wasn't one of your own?
