Also, that part. We are seeing a world where the government(FEDRA) had a quick response to the outbreak and we 20 years into it. They would know how to deal with the infected so they really wouldnt be too much of an issue. I'm sure if we stayed with Joel after his daughter died we we get a lot more infected action.This aspect is kind of secondary though. It isn't really a zombie show.
Compare that to TWD which is based on a comic with stories heavily dependant on zombies. Where everything was overran by zombies. We were with Rick as the outbreak happened and basically stayed with him.
Its a central part of the game, because it's a game and they need the player to do something. With a show you can focus more on the story/characters.Zombies and infected are a central part of the IP.
