'cmon girls and boys - If you don't want money then what do you want? :P
Peace on earth and good will towards men?How about compos that don't run in parallel, like say you could have a shmup-dev compo at a different time than the devcrunch christmas thing?
Just an idea - you might get more submissions to individual compos if they wheren't in competition. I suppose one could make a christmasy ahoot-em up.
