In a sense, your Krusher9 game reminds me of Sword Art Online, a Japanese light novel series.

The story is set at the year 2022, when a virtual reality massively multiplayer online role-playing game called Sword Art Online is released.

With the NerveGear, created by Akiuiko Kayaba ( character in the story), a helmet that stimulates the user's five senses via their brain, players can experience and control their in-game characters with their minds. The Nerve gear and the entire network 

10,000 players log into the Sword Art Onlines' mainframe cyberspace for the first time, only to discover that they are unable to log out. Kayaba appears and tells the players that they must beat all 100 floors of Aincrad, a steel castle which is the setting of Sword Art Online, if they wish to be free. Those who suffer in-game deaths or forcibly remove the NerveGear out-of-game will suffer real-life deaths.

Many stories merge such cyberspace ideas, and all of them hint towards a few years from now. We'll see what the future brings ;)
