The next generation of consoles is opening up opportunities for gamers to go digital and never put a disc in their PlayStation 4 or Xbox One again, but there is one very big problem that is getting in the way of a fully digital gaming experience.

This problem comes down to hard drive space, and new information from Killzone's Guerrilla Games proves this with hard evidence.

According to Guerrilla Games, the development team behind the next gen Killzone game, the Killzone Shadow Fall digital file size is a total of 39.7GB. Firstly, this is a huge amount of space as it is, and would take up close to 10% of the PlayStation 4's 500GB hard drive. Secondly, before Guerrilla Games worked on compressing the file content, the Killzone Shadow Fall digital file size was a massive 290GB.

In a few years' time once the new console generation matures a little, games will only get bigger and better, so it could even be possible that just one game could take up as much as 20% of the PS4's or Xbox One's total hard drive space.

This would completely ruin the idea of a digital gaming experience because you'd only be able to have between 5 and 10 games on your console's hard drive before having to uninstall one and wait a dozen hours for your next game to download.

If Sony and Microsoft are serious about their new digital content approach, they will really need to up the size of the hard drives to match the increasing size in game data.
