You say that Epics move of going free is not aimed at ‘blender-youtube’ kids…
All they do is fishing for that audience. Anyone who has halfway learned how to optimize a game is at least out of school and could afford the tiny $20 they were asking for. And if you think of indie or bigger, then they could even afford more.
UE4 will attract so many ‘Blender-Youtube Kids’ that Epic will drown in their sheer masses. The answer hub already is. They all will want to create their open world dynamic lighting game and they all will hit the fps wall. And then, all that’s left in a few years will be ‘remember UE4? it could not run any game properly that people made! Well, who cares…’.
