every game is linearity
they all allow you to do only wht the developer designs it to do. there are no open ended games. its like life. you can go anywhere in the world, and the moon but the ability to travel into space and the farthest reaches of the Galaxy have not been made yet, and then after that where do you go?
once you reach the end thats it. you go back home, or stay on the planet you liked the most, and repeat the day not doing much different from yesterday.
