The requirements are stupid for you, but not for the people making the project.

>We don’t have an answer to the game engine.

Why do you want to know about the game engine? Do you think that making low poly 3d models is dependent on a game engine? What would be the massive difference between them? Flipping a channel in the normal map?
Also he's looking for a 3d modeller commission, you don't need to know anything else about the game except for the concept they provide you.

>There was nothing wrong with asking questions

You were not asking questions, you want them to change their way of doing things to fit your own needs, you are unemployable.
