Interesting interview with the Plants Vs. Zombies creator in the latest issue of Edge. You can read it online here. The game designer says four people were involved in creating the game: a game designer, programmer, artist, and musician, and it took three years to develop. My guess is that it’s about 8 to 10 man-years of work. I also like the fact that he made the game easy to learn because he doesn’t like opening a game manual (and I can certainly relate to that kind of game design).
It’s an addictive little game. You can get the demo (one hour of play) or buy it on Steam for $10.
