Okay so here we go :D :
- A new paragraph is needed not only for new ideas but separated dialogue, this allows for the story to be much more easily understood and read.
- Detail. It is one's best friend (and sometimes one's worst enemy) but I find that your story lacks it, especially if this were a first chapter. My suggestion would be to edit this to be more like a prologue and instead, give more of a background on the new technology and such. You want the reader to believe they are in the year 2039, and not just thrown into a virtual reality game.
- Continuity is something that even good authors always have to keep tabs on. What we might perceive to make sense in our head may not translate as such on paper. Thus, that is to say we are briefly introduced to the game, then somehow or other Kenny is playing it. Sometimes it helps to backtrack further so as not only be able to explain how he came upon the game, but also to help explain his personality. In so doing, this can help the reader formulate how and why Kenny might react in the game.
Also the sentence "It was two thousand thirty nine when technology broke through." is quite generic, technology everywhere always has its breakthrough. Aside from 'Virtual Wars', what makes that year special?
- Length. While many a times (especially for a prologue) it is not exclusively important, a chapter has a good length, for the reader to get a good grasp at what is happening.
It often times helps to read other people's works, and indeed ask lots of questions if need be. :)
Hope that helps.
