I wanted to make a Tycoon style game where you could make video games using simplified Unreal Engine editor tools, would this violate the terms of the EULA if I distribute it through the Marketplace?
If you include modified editor tools in your game, you can only distribute it to the public who are already Unreal Engine licensees. The only guaranteed way of doing that is through GitHub; we don’t currently have a place for games on the Marketplace. We have started to put some games on the Launcher for modding purposes, like ARK Survival, so that may be an increasing option in the future.
