There's an excellent prototyping policy in effect at Maxis: In terms of time, they have a policy of permission vs. forgiveness. You need to be prepared to fail early – but that’s okay! If a prototype takes less than two days, don’t worry: just go ahead and do it. It if takes more... you should probably have permission. http://www.gamasutra.com/php-bin/news_index.php?story=11628 http://www.gamasutra.com/php-bin/news_index.php?story=11628
