Chris, Boy, I think you both missed the point here, and tom did a great job of twisting an article for the people who don't understand anything. Dev's pay a monthly prescription to use Unreal4. The main devs of UT are making a f2p game and are allowing it to be completely open source. In such that they are inviting devs to come and help make the game with them. Those devs are able to play the game because they are making it. All tom is saying is " if you want to be a dick, and stupid, you can pay to act like a dev for a game in pre-production to play it before it's out".
