Do you think it's worth liking him? Do you think i have a chance with him? im 18 years old?

It isnt worth liking him. He sounds like he would spend time with you but ONLY when you want to like i dont think he would invite you or invite you to spend times with his friends. He seems like he would keep you separate and you would be his last priority and video games would be more of a priority then you and to like someone like that is just a waste of time.
