OASIS (that's an acronym standing for Ontologically Anthropocentric Sensory Immersive Simulation), the virtual reality social network slash MMO in the Spielberg movie Ready Player One that linked all the residents of... well, pretty much the whole world together was a marvel of computer programming and server technology. It offered its users a completely lifelike experience, down to the touch (thanks to the use of VR visors and haptic jumpsuits), all this in the highest definition possible. Imagine the hardware needed to run a simulation of this size, with so many users logged in at the same time. And imagine the bandwidth needed for so many users to be logged on simultaneously—a wireless network (you didn't think Wade's van was connected to a fiber network, did you?) capable of transferring insane quantities of data each second, 24 hours a day. While we have nothing that's capable of such unimaginable bandwidth at this time (although German scientists have already devised a scalable network capable of transferring at least 100 Gbps that can go up to terabits) the upcoming 5G mobile standard can give us a taste of things to come. In short, 5G will change the world—or at least the digital one. Now let's take a better look at what exactly it is and how it will prove to be useful in the future.
In an article published in 2017, author Mark Manson called life "the largest open world game known to date." Come to think of it, he was right—except, of course, that it's not a video game. But did you ever think of just how big Africa really is; it's the second largest continent on our planet. Compared to the real world, open-world games are tiny (except for planet-jumping games—those tend to be pretty big). Still, there are some that have managed to cram massive pieces of virtual land into their gigabytes of files. Let's take a look at some of the biggest open worlds built and released by game developers.
