I dont think they mean any offense or anything its just you get a lot of people come on these Game Engine forums and ask questions like “how can I make this type of game ?”
Basically if you know nothing about making games then you need to start from the very bottom and work your way up. There is no easy way to make a game there is a lot of work needed.
Start with the basic tutorials avilable here and on youtube and try and make a very basic game to start with… Unreal can be used to make any type of game you want really but again you need to learn how.
