Sorry to keep banging on about how different licences work together, but please don't take it as moaning. It is unknown information that I would like to find out. Unity have come up with something really good in Plus, I just hope they are as positive with the EULA. I seem to remember somewhere in the recent kerfuffle a Unity staff member saying this was a positive move for freelancers (but I cannot find the source now), and it potentially is, but also potentially not. If a freelancer is offered work with the team using the Plus licence, that person will also need Plus under the existing terms. If they then move onto another project using the Pro licence, they will now need a Pro licence. The freelancer could need to maintain one of each licence to work with various teams over a year. It has been an issue for me in the past where I have had to turn down Unity contract work because of the need for Pro. In that case I would have had to spend over $5000 on Unity Pro ($1500 Pro + $1500 iOS + $1500 Android, all plus VAT because my income is small and have therefore not registered for VAT), but my income would have been lower than that. It gets better at $1500 + VAT for a subscription (or $1500 + $420, all + VAT if needing both), but it does mean there will be circumstances where income is relatively low, certainly far below $200K pa, but Pro is required. My hope (and therefore a suggestion by putting it here) is that the same licence level must be used within a company, but the limit within a project is not mixing free and paid licences.
