Speaking as a writer, using technical jargon without understanding the meaning will reveal your inexperience with the subject. Sure, people might play the game because of the fluff, but that's all hacking really becomes in games, fluff. Hacking into other systems, as I understand it, is a boring, monotonous process, and even if you do manage to get into another system, it's only a matter of time before you're noticed, if you even manage to get a hold of important information. The easiest method of hacking is acquiring a password, some people do this by using a keylogger, if they have physical access to the machine they're trying to access. Some use viruses, but the distribution of viruses is unpredictable, and if you're trying to gain access to one system, you'd have to rely on someone using that particular machine to access where the virus is contained.
Sure, there is an element of danger to hacking, but that's only being caught and potentially infecting your own machine with viruses you made. Hacking, in terms of telling a story, is downright impractical to capture in a storytelling element as the sole focus of the story, if you're going for accuracy. If you're not going for accuracy, then make it clear that it isn't accurate.
That aside, Basileus put it succinctly: Is the game you're trying to make a fantasy story in disguise?
