To say it's been a bad week for Unity is the understatement of 2023. First they announced a terrible new Pricing scheme, then their customers revolted, as the week goes on though, it gets worse and worse for Unity, from threats from an employee shutting down their offices, to more studios threatening to leave, to scummy secret changes to their terms of service and back door deals with clients to get around the Unity Runtime Fee in an attempt to bury a competitor.
there is no "price difference" they use a completely different pricing model, unity is SaaS, and moving to pay per install. Unreal is free, if you make more than a million dollars then you have to pay 5% royalties to epic.
