Plants vs. Zombies

Plants vs. Zombies in the 'Greatest Tower Defense Games of All Time'? Let's just say, if you've never panicked over a zombie with a cone on its head while frantically planting sunflowers, you've never truly gamed. It's the charm of the undead meeting your garden that makes this game obsessively replayable. Ever tried explaining to someone why you're strategically placing a walnut? Yeah, doesn't sound sane, but in the world of PvZ, it’s high-stakes strategy. This game turns botanists into battlefield generals and that's why it's a tower defense titan.
