We are a gamer household and we have multipul gaming systems. We are always getting the latest games to try. But I find that I still am addicted to Left4dead. I like the new one Left4dead2. But I still find myself going back to the original. It seems that each time its a new game. I love the AI director. The problem I have with so many games out there is that they are just so predictable. So even though the graphics stay the same. The hordes vary so that its reall fast paced and entertaining. Who doesn't like to wade through a zombie horde. We ofcource play it on expert for a real challenge.
