Having gone through the game, tested all modes and strategies, I can confidently say that the game is worth it. It is very addictive, forcing you to test different approaches and strategies. You really feel like a little boss who has to create a successful company on a limited budget. There is no margin for error, and it's a good thing that it's a game and not the real world, as it says at the end of each game session.
The game really shows the capabilities of a simulation that responds to everything you do. Just like in the real world, all your actions have consequences, so it is here. You can't start a campaign without a solid start and hire mindlessly. You have to comprehensively move and pump up your company or you're bound to fail.
My final answer is that behind a seemingly simple idea is a well-honed strategy that reveals the business world from a very important side - the side of responsibility and intelligence.
