I've played that game before. The thing is...games like this one have some similarities to hacking.
I played a hacker app that forced you to wait 3 hours while it "cracked" a password. Even though that seemed like a lifetime I knew it dwarfed in comparison to real cracking, which could take weeks or entire months.
I think these games teach users about the hacker methodology and how to think outside the box. Then we have wargames and such that are more realistic.
