Given that Mystery Crates showed up in Zynga's Café World game on Facebook over the weekend, one might assume that the purchasable crates do make good money for the social gaming company. Granted, the rules have changed for Café World. Unlike the the Mafia Wars model where players can buy multiple crates at a reduced rate, Cafe World Players can only buy a single crate for 10 Café World Cash.
Of course, given that the free way of gaining Café Cash seems to be permanently locked at 5 (10 is needed to buy a Crate), opening a Mystery Case requires a real world money purchase of $4.99 or greater.
