As far as tycoon games go this one is pretty average. There are mistakes and bugs to be found, and there isn't very much to do. But the options that are there are enjoyable. Though you can't customize the look of the phones very much, there are plenty of options for the hardware. The economy of the game is too simple though. If a phone is not the absolute top of the line then it will not sell well. You cannot really make budget phones despite there being a huge market for them in the real world.
