World’s Most Highly Addictive Video Games

Plants vs Zombies

Ah, the blessed Plants vs. Zombies game — the scourge of 11 million people on Facebook and so addictive that it may take an intervention for you to stop playing. This is a tower defense game, meaning that you must use all your resources to protect your tower — your garden.

The more you play, the harder your enemies become, the more you have to defend, and so on. With the leveling aspects of this game unlocking new horrors and new tools for you to cultivate your garden while beating away the ungrateful undead, you’ll be glued to the game for hours.
