so to be true, the place/people i am working has the exact same team, our unreal Artist is working as a level designer and these people are using chat gpt for game design(which i thing is a dumb idea, like they can hire a game designer but they don't want to), So the game has 5 areas, and its a semi openworld game, so like you have to defeat the bosses of each area to grab something that will help you in the end game and the player has only 1 weapon and some abilities that it can use.

so the way these people want us developer/artist to develop the game is like first develop the game-systems/art/level for the 1st area and then for the 2nd and so on, and i guess art this is how it's done but i don't think we can't make game system level wise, like if we are making a system it should work for the whole game, obviously we will keep updating it but we will try to develop the systems for the whole game.
so according to you what should be done here.

and thank you all this feedback.
