The game was goofy as hell, PopCap’s take on a tower defense game pitting Plants vs. Zombies. Well, this comes as a surprise but PopCap has announced the game to be their fastest-selling game of all time. Yes, even more than Peggle and Bejeweled.

PopCap attributes Plants vs. Zombies‘ success to the unqiue gameplay and ability to hold its value even after the player has progressed through  the story mode.

Good job PopCap, you’ve succeeded at making another casual game to rival the addictiveness of World of Warcrack Warcraft.
