Hi @simeongeorge , just want you to give my opinion on the topic.
I dont know your background, but it is always good to have some knowledge if you want to make something. As someone who worked almost his whole life with computers i know they always search a specialist in bigger companies, even i din´t worked myself in the game industrie.
So i would guess picking a direction you like to go would be a good idea in the first place.
And with unreal you have an easy start, i would just play around with the blueprints to find out if you like it. They are really easy to use and you find lots of information and help for it.
