Unreal feels a lot more manual in a sense that you have to know how to put even the simplest things like talking to an NPC together compared to RPG Maker where its as easy as clicking a few buttons. I could have made a whole scene with a handful of premade sprites in RPG Maker with the amount of time it took for me to learn how to put together UI for the dialogue box as well as having an NPC respond to me under the right conditions in Unreal.
Unreal is pretty complex but I don't think it's too hard to get into, especially with the amount of tutorials there are on YouTube. Unreal has a kind of visual scripting they call "Blueprint" where instead of typing in lines of code, you use nodes and connect them in certain ways to execute stuff. Unreal is significantly harder and can be intimidating (sometimes even frustrating when something isn't working right) at times but I've personally found it more rewarding when I learn how to put together a scene, UI, interactions, etc. What's helped not get so overwhelmed with Unreal is being really patient and doing things one step at a time.
