consoles are only good for beat em ups and driving games.

That's what they were designed for.

The only other reason to support consoles is that is gives software developers a standard so that they know what hardware to design their games to.

The PC, however, is flexible, adaptable and upgradable. This means that they can be made to act like consoles for beat em ups and driving games simply by adding a suitable controller and they come into their own with things like simulation games, RPG and Strategy where the controls tend to be more complicated.

PCs also allow game companies to continually innovate new technology as better and better hardware is invented rather than waiting for the next generation to be designed and manufactured together.
