You know, it all really depends on the author, quality, and background of the game. And by background, I mean storyline, plot, etc. But overall, zombie games can be pretty fun. I like those, horror/adventure type games more though, haha.
They aren't good. You don't get the same gorey feeling. They have no blood. You can only see their brains come out. You can do that will a human and have blood.
(sorry for double posts *for people who hate that*)
It sounds like some people have some pretty sick minds... lol. Maybe its good for gamers to love gore?
Well, i love the blood and the gore... but is depend on who is the gamer, me i love blood and gore, but not to point to seriously kill seomeone just for see some blood. ... uh, sometimes i have a allucination and i see a zombie walking in my room but they not really there xD. "That still rare, im just playing too much to horror games." ;P
