Making something better than it was or doing something interesting (good), is important, games companies basicly want people who can make their life easier, that''s not about the language thing though, you can soon learn better English as you go. A game company wants to be able to dump a whole lot of work on you and know you can do it, or they want to make their engine better and think that you can help.
