I voted for 1 week, Soaring Wings is right, a good map takes less than a day to make, plus, in the way, we can add gaps and goals!
And i think i got an idea. 2 weeks, 1 for CAP creation and submission and 1 for judges rating the park in all aspects possible. After the 2 weeks, they pick the winner.
Anyway, at this rate, we might need to start another alpha-testing contest after this one, would you imagine what if we hadn't done a practice contest before starting the actual thing? Not me, for sure!
Things might change mid-way so better start the real one until everything is clear of how will it work for everyone!
