Zombies are all the rage in games these days, even in casual titles like the recently released Plants Vs Zombies tower defense game from PopCap. The game has generated lots of good reviews but according to a new article on Gamasutra it's also generating high sales as well.

How high? According to a quote from PopCap's PR head Garth Chouteau, "At this very early point in its history, it's the best-selling game PopCap's ever had." And that's saying something considering PopCap has also had huge casual game sales with the Peggle and Bejeweled series. Part of the reason is that the game, while still in the casual genre, also appeals to another audience. Chouteau says, "At the moment, we'd estimate that at least half of all buyers of PvZ would fall into the 'hardcore' category." Yep, it's a true "hardcore casual' game and in this game that means big bucks all around.
