Throughout level 1 there are multiple references to what is going on in there world compared to the current real life events that are going on. Some of the references that I noticed were:
There has been news stories in the past that stated that we are running low on Oil.
In the novel there is a real life item called the haptic suit, it allows the user to feel what is happenning in the game at the time. There are also haptic gloves that allow the user "to touch" items in the specific game that the user is playing.
In the novel VR is basically the "normal", it is very common for someone to own one and use one on a daily basis. A new VR has recently been released by the CEO of Facebook which is called the Oculus Quest (The video trailer is below).
