But it seems it’s not worth there effort right now for them. It’s not like Epic is not interested in (i don’t know what they think about it either way;p), but shifting Windows support to UWP seems to be too much of a task and UE4 it self has lot of more important stuff to be done, theres Nintendo NX coming which maybe Epic will want to provide engine for it (UE3 got Wii U support at the end of it lifetime) and probably will be more impotent, as bigger developers that already have UE4 games may want to “port” them to NX, and they can’t do that without Epic (lot of them shifted to UE4 to not need to deal with such stuff). UE4 runs the best on Windows, why would they need rebuild it to UWP right now? UWP seems as good goal for UE5… or else there some barriers i don’t know about as i don’t know much about UWP myself, but indeed it seems to to be a future for Windows devlopment… but Unreal is not yet ready for that.
