Maybe in ten years this won't seem like such a big deal, but today it's almost hard to believeā€”PS4 shooter Killzone: Shadow Fall will be close to a 50 GB download, according to a Sony exec.

Speaking with Eurogamer about the benefits of the next PlayStation's "play while you download!" feature, Sony UK's Fergal Gara dropped the bomb in an interview published this morning:

"The Play as you Download functionality, for example, means you don't need the whole file before you go," Gara said. "This is a little bit counterbalanced by the fact the files themselves are getting bloody big. Killzone: Shadow Fall is an uber file - I think it's cracking on for 50 GB. It looks it, too, when you see it."

Fifty gigabytes! For context, most of the PC's biggest games are closer to 20-30 GB.

The PS4's built-in hard-drive is 500 GB, although not all of that will be accessible for the games and media you download. You can attach an external hard-drive for additional storage, yes, but still! Fifty gigabytes! If the future of gaming is digital, the ever-increasing size of games is going to be something to watch carefully over the next few years.

The Wii U's hard-drive, by the way, is 32 GB. Just throwing that out there.
