Based on your comment it seems like you haven't looked into or used a game engine since the late 90s (Cube 2 and Irrlicht?). The only real open source competition for Unreal and Unity is probably Godot, and it's not really competitive. Many of the engines you mentioned (OSG, Ogre) are not full game engine, but renderers and scene graph implementations. For that something like bgfx or even three.js if you're targeting the browser is a better open source alternative. Most of the engines you mentioned haven't been updated in years and don't have support for modern tech or platforms (VR, AR, DX12, Metal, Vulkan, PS4, XB1, Switch, etc) so you'd be better off writing your own engine if you wanted to actually ship a game. Your advice is like telling someone to license idtech in 2019...

Then put your money towards improving them (or writing your own, if that's cheaper/better?), rather than feeding yet another proprietary hog. By continuing to buy UE you're just digging yourself a deeper hole for when things inevitably turn sour (as they just did for Unity).

  That's an absurd proposition for most people. Rolling out our own worked for Minecraft. It also may work for bigger companies (Frontier Developments, Bethesda?). Successful releases using open-source engines are rare. For the overwhelmingly majority, they are much better off just using one of the big game engines, even after paying them.
