Recently, EEDAR president Geoffrey Zatkin commented on how DLC packages have evolved and changed from the time when the PS3 and Xbox 360 were the main systems, to now when the PS4 and Xbox One have taken over center stage.
"If you went and bought every piece of DLC and averaged them out, in the 7th gen they're basically a tenth of a gig. For 8th gen right now it's basically a seventh of a gig. There's been a huge jump in DLC size, due in a lot of cases to the fidelity you can achieve. And if you look at the hard drive sizes, taking the max size of each one, you can also see there's been a big jump.
"The average DLC size has gone up 8.8 times the amount and the hard drive sizes have gone up about 12.5 times as much.
"Sure the hard drives are a lot larger, but more and more games are putting more game-effecting DLC that people will buy, so on average over time even with bigger hard drives, because people are downloading more DLC in addition to the games they are downloading, I think we're going to start seeing constraints on the amount people can put on a console unless the [manufacturers] start providing extra storage options," Zatkin said.
This does make sense from the correlating standpoint of bigger consoles with more space, equals bigger add-on content for consumers; however, space is still limited on systems like the PS4 and Xbox One.
If we continue to see exponential growth in this area, which one would assume DLC sizes will plateau at some point, then players will quickly find there is no space on their PS4 and Xbox One.
Xbox One owners will undoubtedly find this problem sooner than PS4 owners, mostly due to the fact that they have to install games anyway, and that's before DLCs even come into play.
As we progress through the existences of the PS4 and Xbox One, it'll be interesting to monitor this trend and many others. The industry is evolving and moving toward a more prevalent digital era, and we'll see how not only DLCs change as we go along, but full games themselves.
