One thing I enjoyed about L4D was the special infected. They weren't just your average shambling corpse. They were monsters that required both skill and strategy to defeat. I think why your getting sick of zombie games is because they don't require much skill to defeat. All it takes is a few shots or one nice swing from a crowbar to kill. Zombies are predictable, stupid, and in many games slow. We (that is to say I) kill them probably because I can kill as many of them as I want without feeling morally guilty since they're trying to kill me. In Deadrising 2 the zombies closer resembled gooey bulls eye targets than they did actual threats. What zombie games need to do is make killing a zombie a difficult task. Make it so a zombie is a major threat rather than a small nuisance. I liked "The Zombie Survival Guide" because in some cases, just one or two zombies could take a team of five people to kill.
They need to put the 'horror' back in Zombie survival horror.
