Game Dev Story is a game, where you make games. It is a simulation game, somewhat like The Sims or Simcity, except instead of controlling a town or people, you are running your very own game company. You start out with a small company of about five people, developing games for systems such as the Super Intendro and the Playsystem. Some systems themselves more popular than others. As time progresses you unlock more genres of games to develop, as well as more systems to develop for as time goes on. You get to customize your game in many ways, which can either make it a hit, or a flop. If people like you enough you gain fans, of which on occasion send you fan letters to let you know how you are doing and how much they love your games.
Regardless, before I knew it, I was totally sucked into this game. The accessibility combined with the fact that I love video games (and this game is filled with references, Virtual Kid, anyone?) really makes this an addicted piece that I can't put down. If you own a Droid phone, or even an iPod, I highly recomend this game to you. I picked it up on sale for about 2$, so you might pay more, but it is definately worth the price. I have run my phone battery down quite a few times, and I'm far from done.
In fact, I have a game fro the Gamebox to develop. Its going to be a Shooter - Monster genre game. The last one sold 1 million copies in the first week of sales.
