How is a one-month event 'not timed'?
I think the meaning of that went over your head
It's not a 2 week/one month contest if it isn't possible for somebody to create something truly amazing. Banana Blood God, Freedom in Chains, and Eiyuu are proof of that. Time limits can motivate people to the extremes, to the point where they make the equivalent of a 4 month quest in 2 weeks. Hence, "It's not a timed contest if making something epic isn't possible", because epic things always can, and usually will, come out of timed contests here.
