I’ve been looking for an excuse to post this trailer for “Plants Vs. Zombies,” the latest drug title from casual gaming hit factory PopCap. Now that the tower-defense-style game has officially released, it’s as good a time as any. This little cookie is my early favorite for best gaming-related song of 2009.

Over on the official website, you can download a free demo of the $20 game. If, like me, you’re not much of a PC gamer, you’ll have to hope the rumblings that the game could come to the iPhone and consoles come true.
