Based on the VR worlds being developed, here are the numbers of each job type that the producers estimate they will need. Note that each total person equivalent means that all 12 worlds together will need that many "full time" employees with that skill. For example, 6 video production full time equivalents means that on average each producer will need video production only half of the total of 6 weeks. Another way of looking at it is that if there are more than 6 people in the video production guild, some of them will be out of a job at least part of the time.
