Hotel Giant is a strait-forward hotel simulator. Your domain of operations is limited to the inside of a pre-constructed hotel, which can be as small as a quaint European cottage, or as big as to compete with skyscrapers.
The game has only two modes, Tutorial and Campaign. The Tutorial takes you through a handful of hotels, requiring the completion of certain goals that will not only let you advance to the next hotel, but will also strengthen your skills as a hotel manager. The Campaign mode is a more ambitious version of the Tutorial missions, where you have to complete many more goals in larger hotels that are harder than what you've seen before.
As you begin each mission, your goals are clearly laid out in front of you. Usually they comprise of attaining a certain amount of customers and money each month in an allotted amount of time, but there is a good amount of variety that only reveals itself as you get deeper into the game.
Though the shell of each hotel is pre-made, the insides are usually barren. Fertile grounds reside inside those doors and past the doorman, and it is your job to cultivate the right environments that will draw in the big bucks. Herein lie the meat and potatoes of the game. Creating the layouts for the rooms, bars, restaurants, and other areas of leisure, will be the most important and involving part of the action.
There is only one foolproof way to attract customers, and that is to make them happy. Whether it is through cheap rooms or a bar on every floor, making the lodgers happy is goal number one. Without them, there is no money, and without money, no hotel. Hotel Giant has an easy way to determine what is wrong and what is right about your hotel. You can look at customers individually, and see a list of their complaints and comments, allowing you to address the situation on a more personal level. This also makes for good variety between each mission, even if you go back to ones you've played before.
