I have been using Unity3D and am considering moving to UE4 for the development of my next project. I’m not worried about paying 5% back of the revenue of the game. It seems to be a reasonable fee. However, I am wondering about how freeware works, and whether it is allowed? I sometimes produce freeware, and in some project in the past, I have had a donation button (although that is most for website services).
Also, can anyone tell me how UE4 games produced with the $19 a week engine are later distributed? Do they have some form of DRM platform, like EA or Steam?
Thank you in advance
