Plants vs. Zombies is a tower defense action video game developed and originally published by PopCap Games for Microsoft Windows and Mac OS X, and addition platforms have been developed since the game was released. Plants vs. Zombies director George Fan intended on balancing the game between a "gritty" game and a "sickeningly cute" game which I enjoyed and agree was achieved. Strong strategic elements were included to appeal to more experienced gamers, while keeping it simple to appeal to casual gamers, without many tutorials. He was inspired to make it a tower defense game after both thinking of a more defense-oriented version of a previous title of his, Insaniquarium, and playing some Warcraft III tower defense mods. While he was looking at the towers in Warcraft III, he felt that plants would make good towers. I greatly enjoyed and recommend Plants VS Zombies, the storyline game play is progressive and has many mini-games, challenges and additional content to keep the game entertaining and retaining replay value. Also, the endless survival mode is insane, the zombies, so...many...zombies, they can't be killed fast enough.
