This is a silly complaint.
By making UE4 free, a 15 year old with no money can sit in his/her basement and learn how to build a game. …It’s very similar to how I began.
One day, this young kid could become a highly valued and respected member of the game development industry, pushing the tech and industry in a bold new direction and building things. Why wouldn’t we want them to have this kind of opportunity?! So what if they start out making games you think are dumb?
