One of the new players on the market. It is CryEngine which was rewritten in open source and free way when it was under the name Lumberjack from Amazon studios. Now it is baked by many tech companies, there is easier way to integrate with AWS which could be nice if someone think not only the gamedev projects in the cloud. So because, it is based on CryEngine, this engine like unreal could be really nice if someone think more about graphics side of the game. Due to scripting language like Lua and their own visual script it can be really good alternative for Unreal Engine. The only problem for me is the license, and how it will comply with the AWS cloud. Of course main engine is on the Apache and some parts are in MIT, there are information about other license for some components.
