Since the beginning videogames had been limited to two big keys: the potential that the hardware could offer in each time and the developer's abilities to surpass their limitations and make the most of it. This allowed surprising games which in the technical level seemed to be impossible. This also allowed a sustained development that led us to a time in which photorealism started to be "a stone's throw away" from us.
In this sense, game consoles had an important role. Most people prefer to play computer games, but these game consoles had become the driving force of the industry to an extent that it monopolised the development periods. The time in which games were only created for a computer, which made the most of the hardware, are far gone. Nowadays everything is centred in star game consoles of each generation and this has very clear consequences.
Game consoles have had very positive effects for the videogame world, but they have had negative effects too. Their life cycle has extended in a noteworthy way, something that, join together with de exclusive developments centred on them, has damaged the use of the hardware of the last generation of computers and had also slow down the development of videogames in a broader sense.
