I had an idea while playing The Last Stand union city I finished the game four times but the game would be great if the player could choose to stay in town and play for longer or a game of this genre only finding survivors joining the group and "cleansing" the entire city building defenses for the night etc ... is only an idea
That's a nice idea, it would add the replay value for the game. But I'm afraid it's almost impossible for ConArtists. They will have to remake the entire system: companions, building barricades, ... which will take a lot of time and effort. Just hope they include such feature in a sequel though.
