Here is a suggestion of what I would like to see in the game: I find that the problem of every open-world sandbox game is that, after a while, you run out of interesting things to do. Sure, you can always keep looking for that next can of beans or a better weapon, but personally, I prefer something beyond that. Something that keeps me immersed in the game and keeps me going. My idea for that would be a hidden over-arching objective: collect information about the outbreak of the infection. You could come across files and tapes with info about what has happened in every major city or even hidden bunkers (thus encouraging exploration), and once you have everything together, it would point you towards an underground installation and a key card that opens it. Then you will have to brave the place, get all the intel and proof you can carry and find a radio to call for rescue. Once that is done you would have to make your way to the extraction point for pick-up. After that you would loose your old character, but get to unlock one of a selection of new character classes, like (e.G.) a special forces soldier with his own gear and who is issued a new objective. I think that this would keep the game fresh and exciting for those who want something beyond just staying alive.
