Unreal Engine 4 - You have access to the Unreal Engine Learning platform, where you can get certifications. With Unreal Engine, you can easily change your career path. Access to cutting edge technology. Blueprints will get you started easily. In time you can start to learn C++. While Unity and Unreal were shortly on par in the first years of UE4, for me Unreal has surpassed Unity in every way possible. That being said, Unity still has a big developer community and you can make great games with Unity too.
