User blog comment:LEGOSuperDKong/New rules for CUUSOO (and the end of many popular projects)/@comment-24567264-20131218172820

So, now I sort of get their logic for the no molds/software projects rule. Both of these types of projects would take mass amounts of time (I'm not sure how much) and mass amounts of money to make. With single set projects, once the initial model has been made, a Master Builder could make an official version within an hour to a day (give or take a few months for licensing.) So, CUUSOO is attempting to make final projects simpler, and that way they can release on time.
