Which direction do you consider more promising - game development or business with game parks? I understand that in an ideal it is necessary to combine both these directions plus to add development of own devices. But in any business there are some more profitable directions, and some less.
It seems to me that based on the ratio of costs and profits, it's more profitable to develop games. Plus of this area is in that no investment in infrastructure is required.
You are not quite right to put it. Investments are required less - this is true. But they are required. On server hardware, for tests, on a lot of things that are needed to make a quality product.
