The School of Choice was introduced on December 29, 2011 as the fourteenth non-cash generating property in New York / Manhattan. This is a limited-time-to-upgrade property in which you have 8 days to upgrade to level 10 (or as far as you can). After this period you will no longer be able to upgrade normally. You get to keep the level you reached and are able to build the items. Unlike regular crafting properties, there is no cost-per-item each time you craft. You can craft once every 18 hours.
