Dont bother wasting your time with Unity. Whats the point of learning unity’s workflow and then learning unreal? really lost me there.
Unreal and Cryengine are both AAA standard engines. However none of these engines will make the AI for you. Both have tools to help create AI’s.
Download Unreal engine and start with the basic tutorials and work from there.
Unreal engine has Blueprint visual editor to help you make games without needing to code.
Goto https://www.youtube.com/user/UnrealDevelopmentKit/playlists
you have so many great tutorials to learn this engine.
Be careful when people tell you to use unity. “some” are actually unity plugin developers trying to get more people over to unity so they will purchase their plugins.
I use Unity and unreal engine and I’m not biased. I’m just saving you time and money by learning from my mistakes.
