How long does it take you to design a story?

[Sel]

Most good complete projects take several months to a year or more, with motivation over that period wavering up and down, there's no average time, and you should take however long it takes to make something good, without throwing down a deadline for when it must be finished. If you do, you end up like the games industry with the few studios trying to make creative and innovative titles (Fucked).

Take as long as you need.
