See my full answer on this topic here https://news.ycombinator.com/item?id=7423703 https://news.ycombinator.com/item?id=7423703 to which I can add that we have in fact helped, and are helping, port open source game engines like Ogre3D and Torque. These things do not preclude each other. (Yes, we all have finite time, but helping all such ports is a major priority.) Also, it is not just that they do not preclude each other - they benefit each other as well. For example, you can see some pull requests from Unity developers to emscripten, those fixes and improvements then get to all the projects using it, many (most?) of which are open source. The same goes for fixing a bug that Unity hits, that bugfix benefits all other projects too.
