I addressed the getting the Pro license in my original post, it would double the cross-over point, but that still not very high for a successful freelancer. As for more team members I addressed that afterward in my second post, just before yours came through. Its certainly another aspect to consider and off the top of my head I'd say that Unreal 4 business models real strength here is for small teams of 1-4 people who don't expect to generate more than $100-200k gross profits p.a. After that for larger teams I think things tend to swing back as don't forget you still have to pay your employees from your profits and a larger team means a bigger studio, larger out-goings and thus require consistent profit driven games to be produced. Even taking the highest price comparison point possible, that of buying a new Unity license per person per year including Android and iOS that is $54,000 for the cross-over point. Can you really set up a studio business of 5 people and survive on gross profit of less than $270k? That includes paying each person, paying utility bills, paying for studio space, paying corporation tax etc. Honestly I would not be at all surprised if for a successful business you will exceed the cross-over point between Unreal 4 and Unity costs.
