Plants vs. Zombies

I've played a decent amount of online games in my life, and I have to say that Plants vs. Zombies is strangely addicting. I think there are a few reasons why the game works so well. First, it is a very simple game to get the hang of, making it accessible to just about any audience. Secondly, the game is easy, which keeps it moving along and the audience interested. Thirdly, the game does a good job of constantly adding new elements, whether it's plants or zombies. Overall, I had an enjoyable experience playing the game. My roommates were curious in what I was doing, and soon they were playing too. We all ended up beating the game within an hour, but did not proceed to play the full version of the game. In the end, I can see why this game is popular.
