PopCap Games has an M.O. so strict that many fans just assume it as law; they will release a game on an original platform (mostly PC), and then create further versions for as many systems as they possibly can. Following this trend is the game, Plants vs. Zombies. I am not ashamed to admit that I love this game so much that I own it on PC (twice, in fact), PS3, 360, iOS (twice), and DSiWare. With all these different versions available, is the DS version worth picking up?
