You start the game as a small two star chain hotel manager. For you, life is cheap and your hourly rates are cheaper. Little by little you slowly devour customers and their possessions until you reach critical mass, allowing you to bribe hotel officials and pushing you up a star rating.
Upon reaching a grand total of fire stars, the hotel drops the pretence of accommodation and uproots itself from its earthly bounds and begins rampaging through a downtown of your choosing.
This is where the game really flys off the deep end interms of balance and replayability. Sure its cool watching a Novatel claw its way up the Chrysler building and swat angrily at bi-planes, but after the first time it gets fairly stale.
The controls are dodgy and sluggish (You're a fifteen story hotel, I guess it was intended) and the concept is frankly ridiculously.
I got it for a buck. Don't bother. There are better sentient building simulators out there.
