Glenn, I disagree only because of the chatter on frothers, the Forum of Doom, Reaper forums, etc. about Zombies. For people who are really into them, there are not enough sculpts, ever.
I guess if you're playing a zombie survival game, and you want the feel of a parking lot PACKED with zombies, then you really need all that variety.
It's a popular genre, but like you Glenn, I don't need all of them. Of course, I don't need miniatures at all, and I can stop buying them any time I want. BULL!!
